Em primeiro lugar, fazemos a seguinte discuss\u00e3o de um ponto de vista dial\u00e9tico:<\/p>\n

O trabalho representativo “Introdu\u00e7\u00e3o \u00e0s subst\u00e2ncias de \u00e1cido h\u00famico” mencionou: HA pode ser dividido em tr\u00eas categorias de acordo com a solubilidade, a saber, HA preto, HA marrom (\u00e1cido h\u00famico) e FA. Ent\u00e3o, pode-se entender que FA \u00e9 HA, e ao determinar HA, FA n\u00e3o pode ser exclu\u00edda.<\/li>\n<\/ul>\n

          (1)De acordo com o padr\u00e3o de teste de humato de pot\u00e1ssio agr\u00edcola GB \/ T33804 – 2017, extrair o humato sol\u00favel do humato de pot\u00e1ssio agr\u00edcola com \u00e1gua a uma certa temperatura e, em seguida, usar uma certa quantidade de \u00e1cido para acidificar a gaveta a um certo valor de pH. Depois disso, filtrar com papel de filtro quantitativo de m\u00e9dia velocidade, lavar o precipitado com uma certa quantidade de \u00e1gua, uma pequena quantidade de vezes e secar o precipitado em um forno de secagem a um peso constante. Ap\u00f3s a pesagem, subtrair as cinzas para calcular o teor de HA sol\u00favel.<\/p>\n

          Este padr\u00e3o utiliza as propriedades de que o \u00e1cido f\u00falvico \u00e9 sol\u00favel em solu\u00e7\u00f5es \u00e1cidas, solu\u00e7\u00f5es neutras, solu\u00e7\u00f5es de acetona e etanol.

Ele mostra que este padr\u00e3o suporta que o \u00e1cido fulvico e o HA s\u00e3o duas subst\u00e2ncias separadas.<\/p>\n

          (2)\u00c9 mencionado no padr\u00e3o HGT5334 – 2018 do Minist\u00e9rio da Ind\u00fastria Qu\u00edmica para o fulfato de pot\u00e1ssio que, o \u00e1cido f\u00falvico na amostra \u00e9 extra\u00eddo com \u00e1gua e, em seguida, o HA \u00e9 precipitado com \u00e1cido, e o l\u00edquido supernatante dissolvido na solu\u00e7\u00e3o \u00e1cida \u00e9 a solu\u00e7\u00e3o de \u00e1cido f\u00falvico. .<\/p>\n

          Este padr\u00e3o exclui HA ao testar o \u00e1cido f\u00falvico, tamb\u00e9m suporta que o \u00e1cido f\u00falvico e o \u00e1cido h\u00famico s\u00e3o duas subst\u00e2ncias separadas.<\/p>\n

          Ent\u00e3o, em aplica\u00e7\u00f5es pr\u00e1ticas, que padr\u00f5es devemos seguir para medir o conte\u00fado de HA e o conte\u00fado de FA?<\/span><\/h2>\n

          Em aplica\u00e7\u00f5es reais, como fornecedor de produtos de \u00e1cido h\u00famico, somos obrigados a entender o prop\u00f3sito de uso do cliente e, com base nisso, julgar o produto adequado para os clientes.<\/p>\n

            Entre os novos tipos de fertilizantes, fertilizantes sol\u00faveis em \u00e1gua contendo HA s\u00e3o atualmente os mais populares no mercado. Este fertilizante tem os efeitos de fertilizantes qu\u00edmicos e fertilizantes de \u00e1cido h\u00famico. Al\u00e9m disso, pode aumentar a taxa de utiliza\u00e7\u00e3o de fertilizantes qu\u00edmicos, reduzir o custo de uso dos agricultores e contribuir grandemente para a economia de energia e a redu\u00e7\u00e3o de emiss\u00f5es defendidas pelo governo.<\/p>\n

            Tomemos o produto s\u00f3lido do fertilizante sol\u00favel em \u00e1gua (tipo de elemento principal) contendo HA como exemplo. A determina\u00e7\u00e3o do teor de HA \u00e9 realizada de acordo com os regulamentos de NY \/ T 1971. O princ\u00edpio deste padr\u00e3o \u00e9: o \u00e1cido h\u00famico na solu\u00e7\u00e3o da amostra \u00e9 quantitativamente precipitado sob condi\u00e7\u00f5es \u00e1cidas, depois que o filtrado \u00e9 descartado, o carbono org\u00e2nico no precipitado \u00e9 oxidado com uma solu\u00e7\u00e3o quantitativa de dicromato de pot\u00e1ssio-\u00e1cido sulf\u00farico.<\/p>\n

            Este m\u00e9todo tamb\u00e9m exclui \u00e1cido f\u00falvico, por isso tenha cuidado ao escolher produtos. Se o padr\u00e3o dado pelo fornecedor n\u00e3o exclui o teor de \u00e1cido f\u00falvico ao testar o HA, o fertilizante sol\u00favel em \u00e1gua contendo \u00e1cido h\u00famico produzido com esta mat\u00e9ria-prima ser\u00e1 menor que o padr\u00e3o nacional, fazendo com que o produto n\u00e3o seja qualificado.<\/p>\n

            1. \n

              De acordo com a norma da ind\u00fastria do carv\u00e3o MT \/ T 1182 – 2019, o teor de \u00e1cido h\u00famico sol\u00favel em \u00e1gua nesta norma deve ser implementado de acordo com as disposi\u00e7\u00f5es da GB \/ T 11957. O pr\u00e9 – tratamento da amostra \u00e9 alterado de solu\u00e7\u00e3o de hidr\u00f3xido de s\u00f3dio para \u00e1gua destilada e a an\u00e1lise subsequente n\u00e3o adota a etapa de precipita\u00e7\u00e3o \u00e1cida.<\/p>\n

              Este padr\u00e3o apoia que o \u00e1cido h\u00famico e o \u00e1cido f\u00falvico s\u00e3o a mesma subst\u00e2ncia.<\/p>\n

              Na verdade, n\u00e3o h\u00e1 uma fronteira \u00f3bvia entre humus e n\u00e3o humus.\u00c1cido h\u00famico, \u00e1cido f\u00falvico, humina ou lignina de transi\u00e7\u00e3o, tanino e humus s\u00e3o uma s\u00e9rie de estruturas moleculares de cadeia cont\u00ednua e processos de transforma\u00e7\u00e3o. Portanto, o Sr. Cheng Shaoxin prop\u00f4s que n\u00e3o h\u00e1 necessidade de pressionar muito para nomear consist\u00eancia, apenas a ess\u00eancia e a conota\u00e7\u00e3o s\u00e3o entendidas.<\/p>\n","protected":false},"excerpt":{"rendered":"
