摘要
本文就表面活性剂兰113A(单丁二酰亚胺)兼有载体功能的特点,对其影响乳状液膜提金的若干因素进行了探讨,发现酸度增加,不利于金的提取,而稀释剂1,2-二氯乙烷加入有机膜相中,提取率及内相金谈应同随1,2-二氯乙烷浓度的增加而增大,当有机膜相中1,2-二氯化烷为6%时,内相可得到360μgAu/ml.外相金浓度则由原来的100μg/ml下降到5.8μg/ml.
In this chapter, some factors influencing the extraction of gold were inquired into in accordance with the characteristics of acting as carrier for Lan113A, the result showed that percentage extraction reduced while H+concentration increasing. But, when diluent CH2ClCH2Cl was added to membrane, percentage extraction and concentration of gold in internal phase increased with increasing CH2ClH2Cl, the concentration in the internal phase reached 360μgAu /ml and the concentration of gold in the external phase aecreased from initial 100μg / ml t05.8μg / ml in the condition of 6% CH2ClCH2Cl.
