| 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. |
