| Abstract: | A catalytic spectrophotometric method for the determination of trace dipterex based on its catalytic oxidation of benzidine with H,O, in the presence of weak basic medium of sodium citrate was investigated. The linear range of determination is 0~28. 8 mg/L and the sensitivity is 0.054 mg/L. The method has been used for the rapid determination of trace dipterex with satisfactory results. |
