冷原子荧光测汞仪测定多种物料中痕量汞

Determination of Trace Mercury in Materials by Using Non-dispersive Atomic Fluorescence Spectrometer

研究用冷原子荧光法测定多种物料中痕量汞的测定方法，拟定出一般矿石、锑矿、煤、土壤、硝酸银及污水的硝化及测定方法。试验以普通氮气代替成本高的氩气及高纯氮气。缩短硝化汞的时间为１０～３０ｍｉｎ。

A method for determination of trace mercury in materials by means of non-dispersive atomic fluorescence spectrometry has been tested. Nitration and determination procedures of antimony and other ores, coal, soil, silver nitrate and polluted water have been developed with normal nitrogen as substitute for costly argon and highly purified nitrogen. The reduced nitration time is from 10 to 30 minutes.
