紫外可见分光光度法同时测定水中铬(Ⅵ)和锰(Ⅶ)的含量
Research Simultaneous Determination of Chromium and Manganese in Water with UV Spectrophotometric Method
摘要
Abstract
[ Objective ] The research on the simultaneous determination of chromium (Ⅵ) and manganese(Ⅶ) in water was done. [ Method ] The content of the chromium and ~ese in water was simultaneously tested with the method of UV-visible spectrophotometry at the wavelength of 440 nm and 545nm and according to the additivity of absorbance based on the determination of the absorbance of water under the sulfuric acid as the reference. [Results] The absorbance of chromium and manganese was tested at 440 nm and 545nm wavelength and the regression equations and correlation coefficient after the regression processing of the data indicated that the linear relationship was good. ［ Conclusion] This method was with responsive reaction and simple operation,which was suitable for the simultaneous determination of chromium and manganese in natural water or industrial wastewater.关键词
