【摘要】 研究了pH值、染料浓度、吸附时间、温度对交联精氨酸吸附能力的影响.用精氨酸作单体、戊二醛为交联剂,20℃水浴摇床150 r/m in反应240h,离心,洗涤,冷冻干燥,制备成交联精氨酸吸附剂.在25℃,pH 2.0,吸附剂对日落黄和柠檬黄48h的吸附量分别达到408.92 m g/g和306.96 m g/g,吸附反应符合L angm u ir等温吸附模型.结果表明:方法简单、条件温和;产物对阴离子染料日落黄和柠檬黄有良好的吸附性能.更多还原

【Abstract】 The effects of various experimental parameters such as initial pH,dye concentration,adsorption time and temperature on the adsorption capacity were investigated.The adsorbent was prepared through crosslinking arginine with glutaraldehyde at 20℃ for 240 h on an orbital shake operating at 150 r/min.At pH 2.0,the adsorption capacities of sunset yellow and tartrazine are 408.92 mg/g and 306.96 mg/g respectively.And Langmuir isotherms are very suitable for describing the adsorption process.This preparative method is simple and the reaction conditions are mild.This prepared adsorbent has high adsorption capacities for sunset yellow and tartrazine.更多还原
