An improved method for the selective determination of trace quantities of arsenite and arsenate in plant material

A method is described by which arsenite and arsenate can be determined. The selective determination is based on the significantly different pKa's of arsenious and arsenic acid which are separated by a weakly basic anion exchanger.
