This study aimed to assess the possibility of clay and clay-synthetic zeolite substrates application to immobilization of elements available in municipal landfill leachate. The experimental sorption tests were carried out using the column method to best reflect the actual conditions of elements sorption from percolating leachate in the soil. The leachate sampled in Rokitno, Lublin, Poland, municipal landfill cell was used in the study. Four sorbent substrates were tested: sandy loam sampled in Chotyłów, Poland, its mixture with 10 and 20% by mass of synthetic zeolite NaP1, and synthetic zeolite NaP1. The following elements identified in the leachate were selected for the study: Al, P, Mn, Fe, Sn, and Ba. The elemental concentrations were determined using inductively coupled plasma mass spectrometry (ICP-MS) in accordance with the procedure EPA 6020. The studied sorbents showed good sorption efficiency, however, accompanied by relatively low sorption capacity.
