摘要
制备了双硫腙泡塑 ,研究了双硫腙泡塑富集金的条件和解脱方法。采用液珠萃取比色法进行测定 ,方法的测定范围为 0 0 0 5× 10 - 6 ～xx× 10 - 6 g。经样品验证 ,该方法适用于地质样品中金的快速测定。
The dithizone foam plastics was prepared.The condition of enriching gold by dithizone foam plasties and method of liberating were studied.The colormetric comparison was employed to determine gold in geological sample after liquid beads extraction.The determination range was 0.005×10 -6 ～ xx ×10 -6 g.Verified by sample,this method was suited to quick determine gold in geological sample.
