本文用2—氯丙基乙基硫醚(以S—CPE代表)的异戊醇溶液从盐酸介质中对金的萃取行为及其影响因素进行了研究。在试验的条件下,一级萃取可达95％左右,二级萃取可达定量要求。做了某些常见金属离子的萃取试验,表明试剂具有良好的选择性。
In this paper, 2-chloropropylethyl sulfide (represented by S-CPE) isopentyl alcohol extracted from hydrochloric acid in the gold extraction behavior and its influencing factors were studied. In the experimental conditions, a level of up to about 95% of the extraction, secondary extraction up to quantitative requirements. Do some extraction experiments of common metal ions, indicating that the reagent has good selectivity.
