	将废弃角蛋白水解洗涤过滤制得高纯复合氨基酸，利用水溶液合成法制备复合氨基酸螯合锌，用EDTA滴定法和原子吸收分光光度法分别测定复合氨基酸螯合锌的螯合率，其相对标准偏差分别为2.79%和1.38%。以甲硫氨酸和丙氨酸为例，分别对甲硫氨酸螯合锌和丙氨酸螯合锌进行红外光谱表征，其吸收峰明显减少，说明产物的对称性增加，结合吸收峰的位移变化说明了螯合物的生成。<br />
The high-purity complex amino acid was prepared by washing and filtering the waste keratin, and the corresponding complex chelated amino acidic zinc compounds were prepared by aqueous so-lution synthesis method. The chelated rate of the complex chelated amino acidic zinc compound was determined by EDTA titration and atomic absorption spectrophotometry, respectively. The standard deviations were 2.79% and 1.38%. Taking methionine and alanine as examples, the spectroscopy of zinc methionine and alanine chelate zinc were characterized by infrared spec-troscopy and the amount of the absorption peak was significantly reduced. The change of the dis-placement of the absorption peak indicates the formation of the complex chelatedamino acidic zinc.
