摘要
探讨了巯基棉在不同吸附条件下对水中Cr^(6+)、Ni^(2+)的定量吸附,并用原子吸收分光光度法分别测定其含量。巯基棉吸附效率高,定量解脱完全,待测元素的分离富集选择性强。此法灵敏度高,误差小。
Cr6+ and Ni2* contents in water were determined by the atomic absorption photometric method after quantitative absoption with mercapto-cotton.Mercapto cotton has high absorption,complete quantitative extrication and high selectivity of determining element.The sensitivity of the method is high and the error minor.
