实验研究用3A型沸石吸附硬水中的Ca2＋、Mg2＋,用EDTA络合滴定法测定其总硬度。实验研究沸石用量、溶液酸度、吸附时间及吸附温度对Ca2＋、Mg2＋的吸附效果的影响。结果表明,3A沸石具有较好的硬水软化性能,当沸石用量7 g,当溶液为中性或弱碱性,吸附时间为40 min,吸附温度为40℃时,水样的硬度为84 mgCaCO3/L,达到国家标准,Ca2＋、Mg2＋的吸附率可达96%。
實驗研究用3A型沸石吸附硬水中的Ca2＋、Mg2＋,用EDTA絡閤滴定法測定其總硬度。實驗研究沸石用量、溶液痠度、吸附時間及吸附溫度對Ca2＋、Mg2＋的吸附效果的影響。結果錶明,3A沸石具有較好的硬水軟化性能,噹沸石用量7 g,噹溶液為中性或弱堿性,吸附時間為40 min,吸附溫度為40℃時,水樣的硬度為84 mgCaCO3/L,達到國傢標準,Ca2＋、Mg2＋的吸附率可達96%。
