【摘要】 利用海藻酸钠,明胶,PVA固定化酵母菌吸附金属铅离子,实验结果表明,包埋剂海藻酸钠、明胶、PVA浓度各为1%,pH值为4.5,Pb2+离子初始浓度为0.9652mmol·L-1,酵母菌浓度为5g/L时,在室温下吸附1h,吸附效果最佳,其吸附模型符合Langmuir等温吸附方程。更多还原

【Abstract】 Adsorption of yeast immobilized by alginate sodium,gelatin and PVA on Pb2+ ions was studied in the paper.The experimental results indicated that there was the bdst effect when the concentration of alginate,gelatin and PVA was 1% respectively,pH value was 4.5,the Pb2+ ion initial concentration was 0.9652 mmol.L-1,the concentration of beer yeast was 5 g/L,adsorption time was 1h under the room temperature.Its adsorption model was conformed to the Langmuir iso-thermal adsorption equation.更多还原
