摘要
经对数种不同功能团螯合树脂的研究,优选出了对汞吸附效率高、解脱速度快的H-1S8型螯合树脂,并对树脂装填柱的形状及体积大小进行了研究。对树脂交换与洗脱条件及原子荧光光谱测试条件进行了优化实验。实验结果,方法的检出限为0.002μg/L,测定地面水水样汞的平均浓度为0.009μg/L;精密度实验的相对标准偏差为5.5%,回收率为96％～101%。
Through studying on several kinds of different function group chelate resin, H-188 chelate resin with high adsorption efficiency and desorption speed for mercury was selected, and the shape and volume of the resin filling column were also researched. The optimum experiment wao done on the conditions of resin exchange and determination by AFS. The results were as follows: detection limit was 0.002μg/L, average concentration of mercury in surface water was 0.009μg/L, RSD 5.5%, and recovery rate 96%- 101%.
