摘要
采用静态吸附法研究了花生壳用量、粒径,刚果红溶液pH值、初始浓度,吸附时间,温度6个因素对花生壳吸附刚果红的影响。结果表明,花生壳对刚果红的吸附能力随其粒径的减小而增加;随着吸附时间的延长,花生壳对刚果红的去除率增加,90min时基本达到吸附平衡;在常温下,溶液pH为7.54时,花生壳对刚果红的吸附去除率可达91.2%;花生壳对刚果红的等温吸附较符合Freundlich方程。花生壳可作为吸附去除刚果红的理想功能材料。
Adsorption of Congo Red by peanut shells was studied with a static adsorption method and effects of dosage and size of peanut shells,pH and initial concentration of Congo Red solution,duration of the incubation and temperature on the adsorption were investigated.Results show that the smaller the particle size of peanut shells,the higher the adsorption capacity of peanut shells,and the longer the duration of incubation,the higher the removal rate of Congo Red.However,the adsorption might basically reach equilibrium in 90 minutes.At room temperature,removal rate of Congo Red reached 91.2% in solution 7.54 in pH.The isothermal adsorption behavior of peanut shells on Congo Red tallied quite well with the Freundlich equation.So that,the peanut shell is an ideal functional material to remove Congo Red through adsorption.
