Bacillus mucilaginosus was cultured in the medium containing illite, then the culture was burned in muffle to prepare adsorption material modified by microorganism. The biological modified illite (BMI) was used to adsorb cadmium ions at different conditions. The result showed that BMI had significantly improved Cd adsorption potential compared to original illite; BMI had a good adsorption in the neutral environment; adsorption isotherms of Cd onto BMI followed Langmuir equation and adsorption
