Abstract: Electrocoagulation method for removal of ions of lead, copper, cobalt, nickel, iron, zinc and chromium in acidic, neutral and basic solutions was studies. The initial concentration of each of these ions in the solution was 1,000 ppm. Aluminium plates were used as electrodes. The DC power source was applied during the 2-hour period to the electrolysis unit containing1 litre of solution with the current and electrical potential of 2.2-6.2 A and 17.5-19.0 V, respectively. Under these conditions, coagulation of lead, copper, cobalt, nickel, iron and zinc ions in the three pH values were lfound to be very effective, with 98.00 - 99.99% coagulation, were not suitable for removal of chromium ion (in the form of chromate) from the solution.
