中文摘要:
      采用松树锯末以及改性锯末为吸附材料,以亚罗丹明B的模拟废水为吸附对象,研究了溶液的pH值、吸附时间、锯末投加量及模拟废水初始浓度对吸附效果的影响.研究表明:在最佳条件下改性前后的锯末对罗丹明B的最大吸附量分别为26.81、39.37 mg/g.同时对改性前后的锯末做了吸附等温线拟合及动力学研究,结果表明吸附等温线均能很好地符合Langmuir或Freundlich吸附模式,吸附过程符合拟二级动力学方程.
英文摘要:
      In this paper, the adsorption of Rhodamine B by sawdust (SD) and modified sawdust (MSD) was investigated. Influences such as pH value of aqueous solution , adsorption time and initial concentration of Rhodamine B were studied. The results indicated that the equilibrium capacity were and 26. 81 and 39. 37 mg/g before and after modification respectively at room temperature and under best conditions. At the same time, the adsorption isothermal cure and kinetic equation were simulated to illustrate the adsorpti...
