【摘要】 用甘蔗渣制备甘蔗渣纤维素黄原酸酯,然后将其与Fe3+反应,制得吸附材料甘蔗渣黄原酸酯铁。用此吸附剂吸附水溶液中的苯酚,对吸附pH、温度和时间等工艺条件和吸附动力学进行了研究。研究结果表明:甘蔗渣黄原酸酯铁对苯酚的吸附最佳pH为10.0,温度为40℃,时间为2.0h。不同温度下,甘蔗渣黄原酸酯铁吸附苯酚符合Langmuir等温吸附方程。更多还原

【Abstract】 Bagasse xanthate were prepared by bagasse with CS2,then adsorbents Bagasse xanthate-Fe(Ⅲ)were obtained by Bagasse xanthate reacted with iron ion. Adsorbents were used to remove phenol,and the effects of pH,temperature, adsorption time on adsorption ability and kinetics of Bagasse xanthate-Fe (Ⅲ)on phenol were investigated. The results show that the best conditions were pH 10.0,temperature 30℃,adsorption time 2.0h. The adsorption data showed a good fit with Langmuir isotherm equation.更多还原
