| Resumen |
An alternating-current polarographic method for the determination of 6 metals without prior separation is proposed. The method is based on reducing ions of copper, lead, cadmium, nickel, zinc and manganese at a dropping mercury electrode with a supporting electrolyte of acetic acid and ammonium acetate. Samples are collected and prepared by pumping measured volumes of air through APHA filters, ashing the filters, treating the ash with concentrated hydrochloric acid and taking up the residue in electrolyte. Detection limits are 0.04µg/mL for copper, lead, cadmium and manganese and 0.08µg/mL for nickel and zinc. Iron and chromium do not interfere with the determination. Analysis after dissolving the sample takes about 30 minutes. |
