Differential Pulse Polarographic Determination of Zinc and Manganese in Commercial Sodium Salts and Water Samples after Preconcentration of Their 2-(2-Pyridylazo)-5-diethylaminophenol Chelates Using Ammonium Tetraphenylborate-Naphthalene Adsorbent

A highly sensitive, rapid and economical differential pulse polarographic method was developed for the simultaneous determination of trace amounts of zinc and manganese in commercial sodium salts, mineral water, human hair and environmental waste liquid and solid samples. Ammonium tetraphenylborate-...
