| Abstract: | In this paper a new method for the spectrophotometric simultaneous determination of multi components having hardly interference with each other in mixture was established. The orthogonal-regress design with the multi component standard addition was adopted in this method. This method is applicable to determine nickel, cadmium and zinc in UF 4 by spectrophotometry. The RSD were less than 4%, the recoveries were between 97% and 103%, The results showed that the proposed method has a better accuracy and reliability. |
