| Abstract: | In this paper,a method of simultaneous determination of iorn and vanadium by multi-wavelength linear regression derivative spectrophotometry is proposed.The milar absorptivities of iorn and vanadium are 5.08×10~5 and 2.65×10~5 respectively.The detec- tion limit are 0.005μg.mL~(-1) and 0.0003μg.mL~(-1).The result of performed experiments by adding standard sample is satisfactory. |
