Abstract

The procedure is proposed for X-ray fluorescence determination of sulfate ion in aqueous solutions with preliminary concentrating by the dried-drop technique using a portable energy dispersive spectrometer NITON FXL 959 GOLDD+. The procedure was tested for a wide range of sulfate ion concentrations (10–4200 mg/L) in the course of analyses of groundwater samples from the Over-Jurassic aquifer complex of Moscow region, as well as of the waters draining the sulfide porphyry–copper mineralization of the Nakhodka ore field in Western Chukotka. The procedure was verified by the data of water analyses using ion chromatography and titration techniques.

使用便携式光谱仪通过干滴技术对水溶液中的硫酸根离子进行 X 射线荧光分析

摘要

建议使用便携式能量色散光谱仪 NITON FXL 959 GOLDD+ 通过干滴技术初步浓缩水溶液中硫酸根离子的 X 射线荧光测定程序。在分析莫斯科地区侏罗纪上层含水层复合体的地下水样品以及排出硫化斑岩的水的过程中，对该程序进行了广泛的硫酸根离子浓度（10-4200 mg/L）的测试——楚科奇西部纳霍德卡矿场的铜矿化。该程序通过使用离子色谱和滴定技术的水分析数据得到验证。
