Detecting Trace Cations in Desalinated Water by Inductively Coupled Plasma Emission Spectroscopy
In this paper,the method of measuring Ca,Mg and Al in saline water(ICP-AES)was studied,the analysis conditions were optimized,and detection limit,accuracy and recovery rate of the above ions were determined and evalua-ted.The results show that ICP-AES method can quickly,accurately and stably measure Ca,Mg and Al in desalinated wa-ter,and the detection limits of the ions are:Ca 0.5 μg/L,Mg 0.5 μg/L,Al 2 μg/L,with spike recovery of each ion of 98%～102%and relative standard deviation lower than 1.5%.The method provides feasible way to measure new cations of the water desalination and preparation system of unit 3～6 of Tianwan nuclear power plant,such as Ca,Mg,Al,im-proves the detection capability of water quality,and has great significance for subsequent brine system debugging and in-operation water quality analysis.
