An experiment of the immobilization of heavy metals Cu, Pb and Zn in soil by means of natural zeolite was performed in the laboratory. The natural zeolite employed was from a deposit near the village of Sokyrnytsia in the Ukrainian Transcarpathian region. Sandy soil was contaminated by Cu²⁺, Pb²⁺ and Zn²⁺ nitrates at three contamination levels, 50, 100 and 500 mg/kg of each metal. Sandy soil samples contaminated with three different concentrations of three metal solutions were mixed with 5%, 10% and 20% of zeolite. 200 ml of distilled water was added to each plastic container with soil and zeolite mixtures and left for 1 month. After one month sandy soil samples of 0.5 g from each plastic container were analysed by ICP-OES. Zeolite immobilised metals in the order: Pb²⁺ > Zn²⁺ > Cu²⁺.
