电感耦合等离子体发射光谱法测定西藏日多温泉地热水中11种主次量元素
Determination of 11 Major and Minor Elements in Geothermal Water of the Riduo Hotsprings from Tibet by Inductively Coupled Plasma-Optical Emission Spectrometry
摘要
Abstract
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.关键词
