Abstract Effects of nonylphenol (NP) on the adsorption of cadmium by Pseudomonas aeruginosa X, which is screened from cadmium (Cd) contaminated site was investigated. Experiments were undertaken to study the biosorption of cadmium at NP concentrations of 0、1.0、10.0mg/L respectively. It was revealed that the optimal concentration of Pseudomonas aeruginosa X and pH were 1.0g/L and 7.0respectively with initial Cd2+ concentration of 1.0mg/L and hybrid with NP. With two hours absorbing, the biosorption rate was about 90 %. The results of biosorption by devitalized bacteria and live bacteria indicated that the adsorption ability of devitalized bacteria was better than that of live bacteria. By considering the different concentrations of NP as variables, it was found that the lower concentration of NP has little suppressing effect on the adsorption of Cd2+. But the suppressing effect was significant at higher concentrations of NP. FTIR spectra of bacteria X treating Cd2+ and compound of Cd2+-NP separately indicated that the functional groups of hydroxyl group and amido were involved in the adsorption reaction. Moreover, it indicates that high concentration of NP has a greater impact on the activity of cell surface groups. Thus, high concentration of NP affects the adsorption of Cd2+.
