摘　　要：为了降低马氏珠母贝匀浆液中的重金属镉,以马氏珠母贝贝肉匀浆液为原料,利用柠檬酸对镉良好的结合能力来提取贝肉匀浆中的重金属镉,提取实验考察了柠檬酸浓度、pH、反应时间对贝肉匀浆液中镉提取率的影响,并在单因素试验基础上通过正交试验确定了最佳提取镉的条件。实验表明:当柠檬酸浓度为0.08 mol/Lp,H为3.0,反应时间为4 h时,对重金属镉的提取率达到89.31%。In order to reduce heavy metal cadmium from Pinctada martensii homogenatel,Martensii flesh homogenate as raw material,using the Citric Acid removal heavy metals cadmium from shellfish meat homogenate.The factors of citric acid concentration,pH,reaction time to the influence of removal heavy metals cadmium were investigated.The optimum conditions of removal cadmium were fixed,and the results show that：while the concentration of citric acid was 0.08 mol/L,pH was 3.0,reaction time was 4 h,the extraction rate of cadmium was up to 89.31 %
