西藏地热水的矿化度普遍较高，矿物质种类丰富，本文建立了采用电感耦合等离子体发射光谱（ICP －OES）同时测定西藏日多温泉地热水中11种主次量元素（钾钠钙镁硅硼锂锶砷铁和硫酸根）的分析方法。使用双向观测模式可确保不同浓度元素的同时检出，且地热水采用1％硝酸介质保存，在5周时间内11种元素含量的测定值基本稳定。方法检出限为0．0006～0．0162 mg／L，加标回收率为95．5％～105．8％，精密度（RSD，n ＝10）均小于6％，实际水样的测试结果与传统方法基本吻合。本方法为西藏温泉的水文地球化学研究提供了大量可靠的数据。

Geothermal water in Tibet has a high degree of mineralization with abundant mineral substances. Simultaneous determination of potassium,sodium,calcium,magnesium,silicon,boron,lithium,strontium, arsenic,iron and sulfate radical in geothermal water of Riduo Hotspring by Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES)was developed in this study.Analytical conditions were optimized by application of two-way observation mode to ensure simultaneous determination of the multi-elements in geothermal water.In addition,geothermal water was preserved in 1 % nitric acid and the results of 11 elements after five weeks are stable.This method has a detection limit of 0.0006 -0.0162 mg/L,recoveries of 95.5% -105.8% by standard addition,and relative standard deviation (RSD,n =10)of less than 6%.The analytical results were in good agreement with those obtained by traditional methods.This method provides a number of reliable data for hydrogeochemical research on geothermal water in Tibet.
