In this study, the native and 2,5-diaminobenzene sulfonic acid (DABSA) attached Lentinus concinnus biomasses were utilized for removal of U(VI) ions from solutions. At 25 degrees C, the maximum uranium ion adsorption capacity of the native and DABSA attached fungal biomasses were found to be 118.6 and 539.2 mg/g, respectively, at pH 6.0. The negative Delta G degrees values of U(VI) removal showed that the adsorption procedure were spontaneous. ATR-FTIR data showed that U(VI) ions adsorption the adsorbents was mainly attributed by amine, carboxyl and sulfate groups.
