Determination of Phosphorus in Steel by Ethyl Violet Spectrophotometry
A new system for the determination of phosphorus in steel by adsorbed ionic associations of ethyl violet phosphor vanadium molybdenum heteropoly acid was established by using ethyl violet as color developing agent and non-ionic(O/w)microemulsion(OP/n-C5H11OH/n-C7H16/H2O)as dispersive agent.The method is used for the determination of phos-phorus in iron and steel,the result is more accurate,and it is an ideal determination method and system.
