摘要:重金屬污染是人類面臨的嚴峻環境保護問題之一。本實驗研究了用海藻酸鈉作為吸附劑去除水溶液中重金屬銅離子，以及吸附過程中試驗條件對吸附效果的影響。結果表明吸附過程在10min左右就達到了平衡；在pH為6時吸附效果達到最佳；吸附溫度以30℃左右為宜。

Abstract：The heavey iron pollution is one of serious concerns of envionment protection of human being. In this experiment, the adsorption of sodium alginate to Cu2+ was studied. The results showed that sodium alginate has a good adsorption to Cu2+．The adsorbing equilibriums were reached within 10 minutes．The pH value of the solution had a great effect on the adsorption．When pH was about 6.0，the adsorbing effect was the best．The optional temperiture of adsorption of sodium alginateto Cu2+  was about 30℃.
