| 中文摘要: |
| 为了降低四角蛤蜊匀浆液中的重金属镉,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、pH、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镉的最佳脱除条件。当PASP浓度0.05mol/L,pH为3.0,反应时间为3h,料液比为1:10时,重金属镉的脱除率可达89.77%。研究表明,PASP可用于脱除贝肉匀浆液中的重金属镉。 |
| 英文摘要: |
| Sodium polyaspartic acid (PASP) was used for the removal of cadmium from shellfish meat homogenate of mactra quadrangularis. The effects of PASP concentration, pH, removal time, and ratio of material to liquid on the cadmium removal were investigated, and the conditions of cadmium removal were optimized by orthogonal experiment method. The percent removal of cadmium was up to 89.77% when the concentration of PASP was 0.05mol/L, pH 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. |
