Abstract

In this study,sugarcane bagasse(SB) which was modified by tetraethylenepentamine(TEPA) to obtain its modified derivatives(MSB),was employed as novel bioadsorbent to deal with printing and dyeing wastewater.MSB had excellent absorbability toward organic dye eosin and heavy metal ions Cu²⁺ and Cr³⁺.The factors affecting adsorption efficiency,such as pH, temperature and concentration,were investigated.The results showed that when the pH value of solution was six,the adsorption amount of MSB toward organic dye eosin increased 18 times than that of SB,and adsorption capacity toward heavy metal ions(Cu²⁺ and Cr³⁺) was also much stronger than that of SB.The adsorption process of eosin could be better simulated by Langmuir-type adsorption isotherm.MSB had its maximum capacity toward eosin at 25℃,which reached 399.04 mg/g.The results show that the adsorption behavior of eosin by MSB is much better adapted to the Pseudo-dynamic model of the secondary adsorption.A conclusion can be drawn that MSB is a kind of efficient bioadsorbent for treatment of organic dyeing and electroplating wastewater.
