聚冠醚用于金的分离、富集与测定

Synthesis and property of polycrown ethersseparation,concentration and determination of gold

报道了以新的双酚Ａ型聚冠醚为交换柱的固定相，分离、富集和测定微量金的方法。该法操作简便，结果满意。

Trace gold is collected and determined by using polycrown ether as a new ionexchange resin.In the solution of 02mol/L HCl,the adsorption efficiency for Au is about 99% and it can be eluted off with 04mol/L HCl6%(H2N)2CS.The method is simple and the results are satisfactory.It may be used in the analysis of gold in geological and other samples.
