Determination of Micro-iron by Using 5-Br-PADAP in Ring Oven Method
This paper describes the experiments of determining many metals ions by using sensitive color reagent, called 5-Br-PADAP, in ring oven technique. The color condition of Fe (Ⅱ) ion determined, the method of eliminating disturbing ions and the optimum range of determination were studied. The method could be applied to the determination of micro-iron in zincification effluence.
