摘要
电感耦合等离子体发射光谱仪广泛应用于实验室元素分析。本文采用电感耦合等离子发射光谱法(ICP-OES)同时测定碱性电池生产废水中铁、锌、锰、镍、铜、铅、铝、铬金属元素的含量。实验表明,所测元素线性关系良好,相关系数均大于0.999,相对标准偏差为0.7%~1.4%,加标回收率93.6%~111.8%。该法简便、快速,有较高的灵敏度和较低的检出限,能满足废水中多元素分析的要求。
Inductively Coupled Plasma Optical Emission Spectrometers are widely used in laboratory elemental analysis.The content of Iron,Zinc,Manganese,Nickel,Copper,Lead,Aluminum and Chromium in alkaline battery waste water was determined by ICP-OES.The experimental results show that the linear relationship of the measured elements is good,the correlation coefficients are greater than 0.999,the relative standard deviation is 0.7%~1.4%,and the standard recovery is93.6%~111.8%.This method is simple,rapid,has higher sensitivity and lower detection limit and can meet the requirements of multielement analysis in waste water.
