| 摘 要： | 目的建立涉水用不锈钢管材中镍含量的分光光度检测方法。方法在强碱性溶液中，以过硫酸铵为氧化剂，使镍与丁二酮肟形成红褐色络合物，用分光光度法检测不锈钢管材中镍的含量。结果。该方法相对标准偏差在1.11％-3.37％之间，线性相关系数r在09994～0.9998之间。结论该方法准确可靠，操作简单方便，可广泛应用于不锈钢管材中镍含量的测定，以保证饮用水的质量。

| Abstract: | [Objective]To establish the spectrophotometric determination of nickel in water-related stainless steel tube.[Methods]Nickel and dimethylglyoxime formed brown complex in strong alkali solution,with ammonium persulfate as oxidant.Spectrophotometry was adopted to determine nickel content in stainless steel tube.[Results]The relative standard deviations were 1.11%-3.37%,and the correlation coefficient r was 0.9994-0.9998.[Conclusion]This method is accurate and reliable,with simple operation,which can be widely used in determination of nickel content in stainless steel tube for guarantee of drinking water quality. |
