研究了在阴离子表面活性剂十二烷基硫酸钠（ＳＬＳ）存在下从硫酸硫脲金溶液中用铝粉置换金的条件。结果表明，由于ＳＬＳ的分散、浸润作用，金的置换率显著提高，可满足低含量硫脲浸金液的深度置换回收要求。
The conditions for the replacement of gold with aluminum powder from gold sulfate thiourea solution in the presence of anionic surfactant sodium lauryl sulfate (SLS) were studied. The results show that due to the dispersion and infiltration of SLS, the replacement rate of gold is significantly increased, which can meet the deep displacement recovery requirements of low content of thiourea leaching solution.
