摘要
研究稀硫酸改性花生壳对亚甲基蓝的吸附性能,探讨了吸附时间、初始浓度、pH值、温度等因素对吸附性能的影响,并研究了花生壳的再生和重复使用率.结果显示:改性花生壳对亚甲基蓝的最大吸附率为94.53%,最大吸附量为18.53 mg/g;吸附行为满足Langmuir吸附等温式;花生壳可再生使用.
With dilute sulphuric acid modified peanut shells as adsorbents,adsorption performance of methylene blue was investigated.The effects of time,initial concentration,pH value,and temperature on adsorption capacity were investigated.The results show the maximum adsorption of methylene blue was 94.53%,the maximum adsorption capacity was 18.53mg/g;The adsorption conforms to the equation of Langmuir;the modified peanut shells can be reused.
