| 摘 要： | 铀(Ⅵ)—铬天青S与高分子胺胶束增溶剂形成三元络合物后,其灵敏度大大提高,但选择性较差,不易推广。本试验对铀(Ⅵ)—铬无青S—十六烷基三甲基溴化胺体系进行较详细的研究,试验了形成络合物的最佳条件,共存元素的干扰及其消除方法。实验部分

Photometric Determination of Trace of Uranium(VI)with Chrome Azurol S Cetyl Trimethyl Ammonium Bromide |
| |
| Abstract: | A photometric determination method of uranium with chrome azurol S
cetyl trimethyl ammonium bromide was studied.The optimium conditions were
tested. The interferencewas eliminated by the use of extraction with 5%
TOA-ditolyl solvent in 4.5N
hydrochloric acid medium. This method was applied to the concentration
range of 0.x-2000 ppm uranium. |
