【摘要】：以鋁型材廢渣和酸洗廢水為原料制備聚合氯化鋁鐵。考察了氫氧化鈉堿液濃度、溶出時(shí)間和溶出溫度對鋁溶出效果的影響,采用堿溶法溶出鋁型材廢渣中鋁的溶出條件為:氫氧化鈉堿液濃度4 mol/L,溶出溫度60℃、溶出時(shí)間3 h,鋁溶出率可達(dá)到87.6%。鋁溶出液與酸洗廢水聚合最佳反應(yīng)條件為:p H值為3,聚合反應(yīng)溫度為25℃,攪拌反應(yīng)時(shí)間為2 h,靜置熟化時(shí)間為18 h。制備的聚合氯化鋁鐵中鋁與鐵的質(zhì)量比為3∶1。
[Abstract]:Polyaluminium ferric chloride was prepared from aluminum waste residue and pickling wastewater. The effects of alkali concentration of sodium hydroxide, time and temperature of dissolution on the dissolution of aluminum were investigated. The dissolution conditions of aluminum from aluminum profile waste residue by alkali dissolution were as follows: the concentration of sodium hydroxide alkali solution was 4 mol / L, and the dissolution temperature was 60 鈩，
