摘要
利用流动注射在线萃取技术，以ＭＩＢＫ为萃取剂，用火焰原子吸收分析方法测定地质样品中的痕量金，取得了满意的效果。该法精密度好，无污染，操作简便，测定迅速，且样品不需分离。方法检出限Ａｕ为０．７８×１０－９，精密度为２．３０％。
A method for determination of trace gold in geological samples by online extraction and Flame Atomic Absorption Spectrophotometry has been studied with satisfactory results.The method is simple,rapid,precision and no pollution.The detection limit of gold is 07810-9,the relative standard deviation is 23%.
