    摘要:

    为提高矿源水溶性腐植酸的提取率及产品品质,以云南褐煤及辣椒为试材,研究纳米氧化锌催化H2O2

    Abstract:

    In order to improve the extraction rate and product quality of mineral water-soluble humic acid, Yunnan brown coal is used as experimental materials to study the experimental conditions for the production of water-soluble humic acid organic fertilizer from brown coal by using nano zinc oxide to catalyze brown coal by H2O2 oxygenation.And the pepper is used as experimental materials to the biochemical activity of oxylysis products.The results show that:the extraction rate of watersoluble humic acid can be significantly increased by nano zinc oxide catalytic oxidation of brown coal; the most influential factor on the extraction rate of water-soluble humic acid is the ratio of coal to oxidant amount, followed by the oxidation degradation temperature, and the oxidant concentration has the least influence.The optimized condition is: ratio of oxidant(H2O2)to coal is 0.55,catalyst dosage is 0.8%, degradation temperature is 45 ℃, degradation time is 180 min and H2O2 concentration is 20%.Under this condition, the yield is up to 39.42%.The physical and chemical properties show that the content of carbon and hydrogen will decrease, the content of potassium oxide and active group will increase.The biological activity research show that degradation product could significantly improve the height and SPAD content of peppers.
