【摘要】：以废弃革屑为原料,采用氧化钙水解革屑提取胶原蛋白,采用硫酸将胶原蛋白水解成便于植物吸收的氨基酸和小分子肽,螯合金属铁、锌、铜、锰,制备了微量元素型含氨基酸水溶肥料。硫酸的最佳水解工艺为:水解温度110℃,硫酸用量为胶原蛋白的1.25倍,水解率可达91%。液体中游离氨基酸总量为231g/L,高出行业指标131%。制备的微量元素型含氨基酸水溶肥料符合液体产品的技术指标和重金属限量要求。
[Abstract]:Collagen was extracted from waste leather scraps by calcium oxide hydrolysis. Collagen was hydrolyzed by sulfuric acid to form amino acids and small peptides for plant absorption. Metal iron, zinc, copper and manganese were chelated. Water soluble fertilizer containing amino acids with trace elements was prepared. The optimum hydrolysis process of sulfuric acid is as follows: hydrolysis temperature 110 鈩，
