Abstract
An ion-chromatographic method for the separation and determination of K, Na, Mg, and Al ions, the sum of heavy-metal ions (Fe, Cu, Pb, Cr, S n), and chloride, sulfate, and orthophosphate ions present in amounts of 10(-6) - 10(-5)% in 1% solutions of nonionogenic surface-active sub stances (NSAS) is proposed. We use 10(-3) M HCl and 3 x 10(-3) M HNO3 solutions and a 2 x 10(-3) M solution as eluents to determine K+, Na+, Mg2+, Al3+ cations and ions of heavy and transition metals, respectiv ely. The method proposed is shown to enable reliable evaluation of the purity of NSAS.
