摘要
研究了原子吸收光谱法测定压水堆主回路去污液过氧化氢-柠檬酸溶液中铁、铬、镍、钴的影响因素,选择了合适的测量条件,用合成样品进行了试验.结果表明.铁、钴、镍、铬含量在0.5～5mg·L^(-1)范围的回收率为100%±10%,相对标准偏差为6.0%～10%.
Optimum conditions for the AAS determination of Fe?Cr?Ni and Co in a detergent composing H_2O_2 and citric acid are studied and reported in this paper. For all these elements, a recovery of 100% ?10% is obtained for the concentration range of 0. 5~5mg ?L^(-1). RSD obtained for the determination lies between 6% ~ 10%.
