AbstractAbstract

[en] The polarographic behaviour of tungsten (6) in the ethanol -hydrochloric acid - phosphoric acid solutions containing 8-mercaptoquinoline has been studied using DME-technique. The analytical characteristics of tungsten (6) electrochemical reduction have been found. A new method for tungsten determination in ferrous materials is proposed
