摘　　要：采用响应面法优化棉籽粕复合氨基酸与硫酸锌进行螯合反应的条件,制备复合氨基酸锌螯合物。以pH值、复合氨基酸与硫酸锌质量比、螯合温度为自变量,氨基酸锌螯合率为响应值,利用二次正交旋转组合试验和响应面分析法对制备条件进行优化。结果表明:最佳反应条件为pH5.55、螯合温度51℃、复合氨基酸与硫酸锌质量比3.2︰1,复合氨基酸螯合锌的螯合率为72.15%。The optimal chelating conditions for compound amino acid in cottonseed meal and zinc sulfate were investigated by response surface methodology （RSM）. Quadratic orthogonal rotation combination design and response surface methodology were applied in the chelated conditions with pH, temperature and the mass ration of compound amino acid and zinc chloride as independent variables, while taking zinc amino acid chelate rate as response value in the experiment. The results showed that the optimal reaction conditions were pH5. 55, temperature 51℃, the mass ration of compound amino acid and zinc chloride 3.2 ： 1. Under these conditions, the chelate yield was 72.15%.
