Effects of natural sepiolite amendment on a heavy metals polluted soil and the sorption behaviour of sepiolite with respect to cadmium and zinc were studied by means of batch extractions. Using sepiolite as stabilizing agent,the soluble amount of both metals as well as their readily-extractable fractions are substantially decreased,when a sepiolite dose of 4% is applied,sepiolite has significant stabilizing efect on soluble amount of Cd and Zn as evidenced by a decline of 57. 3% and 41. 4% respectively,while the readily-extractable fractions of Cd and Zn as evidenced by a decline of 42. 8% and 24. 7% for Cd and Zn. The sorption processes of Cd and Pb by sepiolite can be described by Langmuir and Freundlich model. The sorption capacities are pH dependent undergoing a decrease with H + concentration increase. The maximum sorption capacities shown at pH 6 are 12. 3 mg/g and 6. 80 mg/g for cadmium and zinc,respectively.
