| 摘 要： | 建立了一种利用连续流动-分光光度法测定固废中氰化物的浸出毒性的方法,当氰化物浓度在0~200μg/L范围内,校准曲线的相关系数r为0.9998;方法的检出限可以达到0.33μg/L;不同浓度样品测定的相对标准偏差低于2.6%,实际固体废物样品加标回收率为96%~103%,方法精密度良好并且准确度较高;通过实际样品测定结果比对,证明方法与传统国家标准方法测定结果有着较高的吻合度,具有良好的应用前景。

| Abstract: | In this paper,the analysis method for the determination of leaching toxicity cyanide in solid waste by continuous flowing spectrophotometry has been developed.The result indicated that linear curve was obtained in the range of 0-200μg/L with a good linearity.The linear correlation coefficient could reach 0.9998 and the limit of detection was 0.33μg/L.The precision is less than 2.6%,the recoveries of real samples are between 96%-103%,the continuous flow injection method has good agreement with traditional GB method in determination of real sample. |
