摘要
采用共沉淀法制备Mg-Al水滑石吸附剂,考察了水滑石对饮用水中氯化物的吸附性能,研究了吸附温度、溶液pH值、吸附剂投加量、吸附时间对吸附量的影响。结果表明,水滑石因具有独特的结构,具有良好的吸附和离子交换性能,能有效去除地下饮用水中的氯化物,具有可再生特点,操作方法简单、成本较低、易于推广。
This paper focuses on Mg - A1 hydrotalcite adsorbent prepared by coprecipitation. The adsorption properties of the chloride in drinking water were investigated. The effect of temperature, adsorption pH, absorbent dosage and adsorptive time on the adsorption capacity was investigated. The results showed that the hydrotalcite has a unique structure, good adsorption and ion - exchange properties. The chlorine in underground drinking water can be effectively removed by Mg - A1 hydrotalcite adsorbent. The method has the characteristics of renewable, simple operation, low cost and easy popularization.
