【摘要】 本文研究改性少根根霉对钍(IV)的吸附。在30℃,起始pH=4.0时,未改性少根根霉对钍的饱和吸附容量可达198.7 mg/g干菌。用NaOH改性处理后少根根霉的吸附能力有较大提高,在30℃,吸附反应的最佳pH范围在4~4.5时,其饱和吸附量为265 mg/g干菌。更多还原

【Abstract】 In this paper,we studied on thorium biosorption by modified Rhizopus Arrhizus,which afford reliance to treat thorium-containing wastewater.The adsorption capacity of thorium was up to 198.7 mg/g when the temperature was 30℃ and the pH was 4.The adsorption capability was improved greatly after Rhizopus Arrhizus was modified by NaOH.At 30℃,when the pH was 4～4.5 which was the optimum pH,the adsorption capacity of thorium was up to 265 mg/g.更多还原
