\u00bfEs el \u00e1cido f\u00falvico (FA) un tipo de \u00e1cido h\u00famico (HA)? Cuando se determina Humato de potasio<\/a> que contiene \u00e1cido f\u00falvico, \u00bfel contenido de \u00e1cido h\u00famico incluye el contenido de \u00e1cido f\u00falvico?<\/span><\/p>\n

\"\"<\/p>\n

En el actual proceso de detecci\u00f3n de Potasio \u00e1cido fulvico<\/a> En China, a menudo se encuentra con una pregunta: \u00bfEs el \u00e1cido f\u00falvico \u00e1cido h\u00famico?\u00bfPuede considerarse que el \u00e1cido f\u00falvico es un tipo de \u00e1cido h\u00famico?<\/p>\n

Primero, hacemos la siguiente discusi\u00f3n desde un punto de vista dial\u00e9ctico:<\/p>\n

    \n
  1. \n

    Suponiendo que el \u00e1cido f\u00falvico (FA) es \u00e1cido h\u00famico (HA), se puede considerar que el FA est\u00e1 contenido en el HA.<\/span><\/h3>\n<\/li>\n<\/ol>\n
      \n
    • Cheng Shaoxin (ex miembro del grupo de expertos del Comit\u00e9 Profesional de Fertilizantes Qu\u00edmicos de la Sociedad de la Industria Qu\u00edmica de China, director de la Asociaci\u00f3n de la Industria de \u00c1cido Humico de China y miembro del Comit\u00e9 Profesional de \u00c1cido Humico de Turba de la Sociedad de Carb\u00f3n de China). Se retir\u00f3 en noviembre de 1999 y ha estado participando en la firma hasta ahora. Consultor de tecnolog\u00eda de la HA, director de la Asociaci\u00f3n de Trabajadores de la Vieja Tecnolog\u00eda y proporcionar consultas voluntarias para las empresas nacionales de HA relevantes.) El trabajo representativo \u00abIntroducci\u00f3n a las sustancias de \u00e1cido h\u00famico\u00bb mencion\u00f3: HA se puede dividir en tres categor\u00edas de acuerdo con la solubilidad, a saber, HA negro, HA marr\u00f3n (\u00e1cido h\u00famico) y FA. Entonces se puede entender que FA es HA, y al determinar HA, FA no puede ser excluido.<\/li>\n<\/ul>\n

      \"Assuming<\/p>\n

        \n
      • En la actualidad, el sistema de clasificaci\u00f3n y denominaci\u00f3n de \u00e1cido h\u00famico universalmente reconocido en China y en el extranjero fue propuesto por Kononova de Rumania, como se muestra en la siguiente tabla:<\/li>\n<\/ul>\n\n\n\n\n\n\n
        materia org\u00e1nica del suelo<\/td>\n1, No humus – Residuos de animales y plantas frescos e inadecuadamente descompuestos<\/td>\n<\/tr>\n
        2, Humus<\/td>\n(a) Sustancias de humus: Incluyendo HA negro, FA, humina y \u00e1cido himatomel\u00e1nico.<\/td>\n<\/tr>\n
        b) Sustancias no humus: Los productos de descomposici\u00f3n fuertes de residuos biol\u00f3gicos y productos resint\u00e9ticos por microorganismos, incluidas las prote\u00ednas, los carbohidratos, las ceras, las resinas, las grasas, los taninos, la lignina y sus productos de descomposici\u00f3n.<\/td>\n<\/tr>\n
        <\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

        Se puede juzgar de esta tabla que el \u00e1cido HA incluye \u00e1cido FA en China y en el extranjero.<\/p>\n

          \n
        1. \n

          Suponiendo que el \u00e1cido f\u00falvico (FA) es una sola sustancia, y el \u00e1cido h\u00famico (HA) es una sustancia separada, es necesario excluirse mutuamente al probar los dos.<\/span><\/h3>\n<\/li>\n<\/ol>\n

          \"Assuming<\/p>\n

          (1)De acuerdo con el est\u00e1ndar de prueba de humato de potasio agr\u00edcola GB \/ T33804 – 2017, extraiga el humato soluble del humato de potasio agr\u00edcola con agua a una cierta temperatura y luego use una cierta cantidad de \u00e1cido para acidificar el caj\u00f3n a un cierto valor de pH. Despu\u00e9s de eso, filtra con papel de filtro cuantitativo de velocidad media, lava el precipitado con una cierta cantidad de agua, una peque\u00f1a cantidad de veces y seca el precipitado en un horno de secado a un peso constante. Despu\u00e9s de pesar, restar la ceniza para calcular el contenido de HA soluble.<\/p>\n

          Esta norma utiliza las propiedades de que el \u00e1cido f\u00falvico es soluble en soluciones \u00e1cidas, soluciones neutras, soluciones de acetona y etanol. El \u00e1cido f\u00falvico disuelto en agua se excluye durante el an\u00e1lisis y s\u00f3lo se utilizan las sustancias precipitadas con \u00e1cido. Esto demuestra que esta norma apoya que el \u00e1cido f\u00falvico y el HA son dos sustancias separadas.<\/p>\n

          (2)Se menciona en el est\u00e1ndar HGT5334 – 2018 del Ministerio de Industria Qu\u00edmica para el fulfato de potasio que, el \u00e1cido f\u00falvico en la muestra se extrae con agua y luego el HA se precipita con \u00e1cido, y el l\u00edquido sobrenadante disuelto en la soluci\u00f3n \u00e1cida es la soluci\u00f3n de \u00e1cido f\u00falvico. .<\/p>\n

          Esta norma excluye el HA cuando se prueba el \u00e1cido f\u00falvico, y tambi\u00e9n sostiene que el \u00e1cido f\u00falvico y el \u00e1cido h\u00famico son dos sustancias separadas.<\/p>\n

          Entonces, en aplicaciones pr\u00e1cticas, \u00bfqu\u00e9 est\u00e1ndares debemos seguir para medir el contenido de HA y el contenido de FA?<\/span><\/h2>\n

          En las aplicaciones reales, como proveedor de productos de \u00e1cido h\u00famico, estamos obligados a comprender el prop\u00f3sito de uso del cliente y, en base a esto, juzgar el producto adecuado para los clientes.<\/p>\n

            \n
          1. \n

            Aplicaci\u00f3n de fertilizante soluble en agua que contiene \u00e1cido h\u00famico<\/span><\/h3>\n<\/li>\n<\/ol>\n

            Entre los nuevos tipos de fertilizantes, los fertilizantes solubles en agua que contienen HA son actualmente los m\u00e1s populares en el mercado. Este fertilizante tiene los efectos de los fertilizantes qu\u00edmicos y de los fertilizantes de \u00e1cido h\u00famico. Adem\u00e1s, puede aumentar la tasa de utilizaci\u00f3n de fertilizantes qu\u00edmicos, reducir el costo de uso de los agricultores y contribuir en gran medida al ahorro de energ\u00eda y la reducci\u00f3n de emisiones defendidas por el gobierno.<\/p>\n

            Tomemos el producto s\u00f3lido de fertilizante soluble en agua (tipo de elemento principal) que contiene HA como ejemplo. La determinaci\u00f3n del contenido de HA se lleva a cabo de acuerdo con las normas de NY \/ T 1971. El principio de esta norma es: el \u00e1cido h\u00famico en la soluci\u00f3n de muestra se precipita cuantitativamente en condiciones \u00e1cidas, despu\u00e9s de que el filtrado se descarta, el carbono org\u00e1nico en el precipitado se oxida con una soluci\u00f3n cuantitativa de dicromato de potasio-\u00e1cido sulf\u00farico.<\/p>\n

            Este m\u00e9todo tambi\u00e9n excluye el \u00e1cido f\u00falvico, por lo que tenga cuidado al elegir productos. Si el est\u00e1ndar dado por el proveedor no excluye el contenido de \u00e1cido f\u00falvico cuando se prueba el HA, el fertilizante soluble en agua que contiene \u00e1cido h\u00famico producido con esta materia prima ser\u00e1 inferior al est\u00e1ndar nacional, lo que har\u00e1 que el producto no est\u00e9 calificado.<\/p>\n

              \n
            1. \n

              Humato de potasio y humato de sodio se utilizan como aditivos para briquetas<\/span><\/h3>\n<\/li>\n<\/ol>\n

              De acuerdo con la norma de la industria del carb\u00f3n MT \/ T 1182-2019, el contenido de \u00e1cido h\u00famico soluble en agua en esta norma se implementar\u00e1 de acuerdo con las disposiciones de GB \/ T 11957. El pretratamiento de la muestra se cambia de soluci\u00f3n de hidr\u00f3xido de sodio a agua destilada y el an\u00e1lisis posterior no adopta la etapa de precipitaci\u00f3n \u00e1cida.<\/p>\n

              Esta norma apoya que el \u00e1cido h\u00famico y el \u00e1cido f\u00falvico son la misma sustancia.<\/p>\n

              De hecho, no existe una frontera obvia entre humus y no humus. El \u00e1cido h\u00famico, \u00e1cido f\u00falvico, humino o lignina de transici\u00f3n, tanino y humus son una serie de estructuras moleculares de cadena continua y procesos de transformaci\u00f3n. Por lo tanto, el Sr. Cheng Shaoxin propuso que no hay necesidad de presionar demasiado para nombrar la consistencia, solo se entiende la esencia y la connotaci\u00f3n.<\/p>\n","protected":false},"excerpt":{"rendered":"
