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, Sn), and chloride, sulfate, and orthophosphate ions present in amounts of 10{sup {minus}6} - 10{sup {minus}5}% in 1% solutions of nonionogenic surface-active substances (NSAS) is proposed. We use 10{sup {minus}3} M HCl and 3 x 10{sup {minus}3}M HNO{sub 3} solutions and a 2 x 10{sup {minus}3}M solution as eluents to determine K{sup +}, Na{sup +}, Mg{sup 2+}, Al{sup 3+} cations and ions of heavy and transition metals, respectively. The method proposed is shown to enable reliable evaluation of the purity of NSAS.
