火焰原子吸收法中氘灯对测定高盐废水中镍的影响

Effect of Deuterium Lamp on Determination of Nickel in High Salt Wastewater by FAAS

三元前驱体行业产生的含镍废水含盐量较高,对镍的分析检测灵敏性和准确性影响较大。在本论文中采用火焰原子吸收法在开氘灯的情况下测定高盐废水中的镍,该方法能有效地测定镍含量,相对误差在7.2%以内,回收率在103.4%~106.8%范围,能够满足分析检测的灵敏性和准确性。

The nickel wastewater produced by ternary precursor industry has a high salt content,which has a great influence on the sensitivity and accuracy of nickel analysis and detection.In this paper,the flame atomic absorption method is used to determine the nickel in the high salt wastewater with deuterium lamp on.The method can effectively determine the nickel content,the relative error is within 7.2%,and the recovery is in the range of 103.4%~106.8%,which can meet the sensitivity and accuracy of analysis and detection.
