摘要
研究了表面活性剂TritonX - 1 0 0 -辛醇析相法对Au -硫代米蚩酮络合物的萃取行为及机理。该法简便快速 ,能在常温下析相 ,络合物的稳定性大大增强 ,萃取效率高。将该法用于地质样品中痕量金的测定 。
The lyotropic liquid crystalline extraction spectrophotometric method for determining the trace gold was investigated.The mechanism of the extraction was discussed.This method is simple,convenient and high efficiency.It is suitable to use at ambient temperature,and the complex is stable.This method has been applied to determine trace gold in the geological samples with satisfactory results.
