摘　　要：以四角蛤蜊贝肉匀浆液为材料,利用聚天冬氨酸(PASP)对镉的优良结合能力来脱除贝肉匀浆液中的重金属镉。考察了PASP浓度、p H、脱除时间、料液比对贝肉匀浆液中镉脱除率的影响,并在单因素试验基础上通过正交试验确定了脱除镉的优化条件。在PASP浓度0.05mol/L,p H 3.0,反应时间3h,料液比1∶10条件下,重金属镉的脱除率可达89.77%。因此,PASP可用于脱除贝肉匀浆液中的重金属镉。Sodium polyaspartic acid（ PASP） was used for the removal of cadmium from shellfish meat homogenate of mactra quadrangularis. The effects of PASP concentration,p H,removal time,and ratio of material to liquid on the cadmium removal rate were investigated,and the conditions of cadmium removal were optimized by orthogonal experiment method. The removal rate of cadmium was up to 89. 77% when the concentration of PASP was0. 05 mol / L,p H was 3. 0,removal time was 3 h,and the ratio of material to liquid was 1∶ 10. Therefore,PASP was suitable for the removal of cadmium from shellfish meat homogenate.
