摘要/Abstract

摘要：

近年来，随着各种新技术在金矿找矿领域中的应用，越来越多的化探样品弱异常需要更准确的测定方法。采取添加抗坏血酸、增加溶液浓度及引进密封溶样技术等方法和措施，改进薄膜塑料吸附—石墨炉测定痕量金的方法，降低了方法检出限，实现了低含量化探样品的准确测量。通过改进方法，提高了生产效率，降低了成本，减少了对人体的伤害，取得了较好的效果。

关键词: 石墨炉原子吸收, 检出限, 封闭溶样, 痕量金

Abstract:

In recent years,as all kinds of new technologies were applied in the gold prospecting area,more and more geochemical samples requested more accurate measurement method for determination of a weak anomalies. We took effective measures of adding ascorbic acid,increasing solution concentration,bringing a kind technique of seal completely to improve measuring methods of trace gold with the foam plastic adsorption-graphite furnace.Furthermore, it reduced the method detection limit and improved accurate precision of low content geochemical samples.These methods could improve the production efficiency,reduce cost,and injury to persons,achieve good results.

Key words: Graphite furnace atomic absorption, Determination, Sealing dissolved samples, Trace gold
