摘要
本文报道了采用黄原酯棉(CCX)在煮沸过的王水介质中富集分离金的研究。确定了CCX吸附金的最佳条件和解脱金的方法,并拟定了应用火焰和无火焰原子吸收测定金的方法。本法简单快速、选择性好、准确度高。方法的灵敏度为:火焰法:2μg、无火焰法:5ng。经样品验证,结果满意。
A study of preconcentration/preseparation of gold by cotton cellulose xanthate (CCX) in boiled aqua regia has been reported. Conditions of adsorption/desorption of gold are optimised and the procedures of gold determination by FAAS and GFAAS have been established. The method is simple, rapid, accurate and sensitive with the detection limits of 2 μg for FAAS and 5 ng for GFAAS. The results with sample tests are satisfactory.
