摘要
用共沉淀法制备了n(Mg)/n(Al)=2∶1的铝镁水滑石,并用红外光谱仪对铝镁水滑石进行了分析。研究了吸附时间、吸附温度、吸附剂用量等条件对吸附量的影响。实验结果表明,在最适温度为30℃、吸附时间为3.0 h、铝镁水滑石用量为0.2 g时,水滑石吸附氯离子比较符合Langmuir吸附等温式,饱和吸附量为21.67 mg/g。
Al-Mg hydrotalcites with Mg/Al ratios 2 are prepared by using a coprecipitation method and the products are analyzed by an infrared spectrometer.The influence on the adsorptive time,tempreture and its dosage to the adsorption capacity is studied and the result shows that the situation of hydrotalcite adsorption to chloride ion is accord with Langmuir isotherm formula and the saturation adsorption quantity is 21.67 mg/g under the condition of temperature 30 ℃,time 3 hours and dosage of hydrotalcite 0.2 g.
