| Abstract: | The immobilized activated sludge particles were prepared using sodium alginate and polyvinyl alcohol as imbedding agent.The optimal conditions were chosen in terms of the mechanical stability,particle size,and the level of difficulty for forming particles.The effect of adsorption for the particles prepared under the optimal conditions on the lead ion was studied.The results showed that the optimum conditions for the adsorption of the activeed sludge to lead ion were: the time for adsorption equilibrium of 120 min,the pH value of 7 and the adsorption temperature of 30℃. |
