Abstract
The invention relates to the field of treating water, industrial and domestic sewage. A method of extracting heavy metal ions from sewage consists in filtering the sewage through a saw-dust charge treated in the water medium at a temperature of 90 to 400°C in the presence of a 5 to 10 % solution of sodium polysulphide or ammonium polysulphide.
