| 摘 要： | 采用双硫腙萃取分光光度法分别测定用三种不同方法处理的同一载银活性炭样品。在工作波长mλax=462nm处测定,线性范围为0.5mg/L￣3.0mg/L,线性相关系数为1.00。通过比较不同方法处理的样品的Ag+含量,得出了处理和测定载银活性炭中Ag+含量的最佳方法:载银活性炭加NaCl,在镍坩埚中熔融后用浓氨水溶解,并用双硫腙萃取分光光度测定其中Ag+含量。

| Abstract: | The Ag-loaded activated carbon(AAC) treated by 3 different methods was detected by spectrophotometry extracted by dithizone.The linear range is 0.5mg/L～3.0mg/L at a wavelength of 462nm with a coefficient of 1.00.Through comparison of the different Ag contents in AAC treated by different methods,an optimum method to detect the Ag content is obtained.The AAC added with NaCl was melted in the nickel crucible,and then dissolved in strong ammonia.Finally the Ag content was detected with spectrophotometry extracted by dithizone. |
