Simaltaneous Spectrometric Determination of Tungsten and Molybdenum by the Calculated Method

Li Hua;Cui Zhimin;Kang Dingxue(Departmetn of Chemistry and Chemical Engineering, Henan University)  
The linear regression method of multi-wavelength data was applied to the detemination of W and Mo in the ternary complexes of PV-CTMAB - W, Plus Mo system. The spectrophometric characteristie of the system,optimum conditions for the complex formation and effects of foreign ions were studied.The absorbances of the mixture contained W and Mo were measured at many wavelengths,and the data were treated by linear regression method to evaluate the coneentration of W and Mo.In the range from 650 um to 690 nm, the RSD(%) was less than 8% for microamOunts of W and Mo with eoneentration ratio from 1: 3 to 6: 1
