摘要
采用德国斯派克BLUE型电感耦合等离子发射光谱仪同时测定地下水中的铁、锰、锌、铅、铬、镍、铝、钾、钠等多种金属离子.回收率在93.2%~107.0%之间,线性相关系数大于0.9990,相对标准偏差介于0,13%~1.15%,测定灵敏度、精密度和准确度均满足有关水质分析标准要求.该方法具有样品前处理简单,干扰少,测定快速准确,可进行多元素同时分析。
adopting Germany spectro BLUE type inductively coupled plasma emission spectrometer in the simultaneous determination of groundwater iron,manganese,zinc,lead,chromium,nickel,aluminum,potassium,sodium and other metal ions.The recovery was between 93.2%~ 107.0%,the linear correlation coefficient is greater than 0.9990,the relative standard deviation is between 0.13%~ 1.15%,measurement sensitivity,precision and accuracy can satisfy the requirements of standards related to water quality analysis.This method has some advantages such as simple sample preparation,less disturbance,fast and exact,determination for multielement analysis at the same time.
