[0031] The preparation method of the humic acid type green environmental protection antibacterial anti-insect pheromone medicament comprises the following steps:
[0032] 1) Weigh the weathered coal sample after 120 mesh drying, add dilute hydrochloric acid at a ratio of 1g:(10-25) mL of solid-liquid ratio, heat and boil to activate, wash the precipitate to neutral after cooling, and then press 1:(8 The solid-to-liquid ratio of ~10) was added with 10% ~ 20% sodium hydroxide solution, heated and stirred in a boiling water bath at 100°C for 1 ~ 3 hours, cooled to room temperature, centrifugally filtered, and weighed the quality of the impurities after alkali dissolution; Add dilute hydrochloric acid to the filtrate to adjust the pH to 1-3, let it stand for 24 hours, filter it, collect the precipitate and dry it to constant weight to obtain humic acid.
[0033] 2) Weigh 1 g of humic acid and dissolve it in 10 mL (20%) of a strong alkali with a pH of 11 to 14 to obtain a humate so...
