title: Sodium di-n-propyldithiophosphinate and activated carbon used for the concentrating of bismuth and its determination by atomic emission spectroscopy with inductively-coupled plasma.
abstract: Sodium di-n-propyldithiophosphinate has been proposed as a reagent to improve the sorption properties of activated carbon. The conditions for sorption concentration and separation of bismuth from aqueous solutions were studied. Possibilities for desorption and subsequent determination of bismuth by atomic emission spectroscopy with inductively-coupled plasma were shown.
