| Abstract: | A spectrophotometric and a first derivative spectrophotometric methods have been proposed respectively for determining nickel in ammoniac medium using sodium periodate as oxidant and dimethylglyoxime as color reagent and for the determining palladium in sulfuric acid medium using ascorbic acid as protector and potassium iodide as color reagent.These methods are rapid,accurate and reproducible.The recommended methods have been successfully applied for the determinations of nickel and palladium in the electroplated layer. |
