Abstract

ABSTRACT The use of low-cost and eco-friendly adsorbents has been investigated as ideal alternatives to the current expensive methods for removing dyes from waste water. Orange peel (OP) was used as a low cost natural waste adsorbent for textile dyes from aqueous solution. The effectiveness of (OP) in adsorbing ;C.I. Direct Red 79 (DR 79) and C.I. Direct Yellow 27 (DY 27) from their dye baths has been studied as a function of pH, solid/liquid ratio, agitation time and initial dye concentration. The sorption isotherms were analyzed using Langmuir and Frendlich models. The results indicated that acidic solutions supported the adsorption of the studied dyes within (OP). Adsorption kinetic models were analyzed using the pseudo-first, second order equation and intraparticle diffusion equation. The results showed that the order equation fitted the experimental data very well. By the way, the effect of adsorbent surface was analyzed by scanning electron microscope (SEM), whereas the SEM images showed reasonable agreement with adsorption measurements.

桔皮作为环保型纺织印染废水吸附剂的应用前景

研究了低成本和环保吸附剂的使用，作为目前昂贵的废水染料去除方法的理想替代品。研究了柑桔皮作为一种低成本的天然废染料吸附剂，从水溶液中吸附纺织染料。(OP)的吸附效果研究了直接红79 (DR 79)和直接黄27 (DY 27)对pH、料液比、搅拌时间和初始染料浓度的影响。采用Langmuir和frendich模型对吸附等温线进行了分析。结果表明，酸性溶液有利于染料在(OP)中的吸附。采用拟一阶、二阶方程和颗粒内扩散方程对吸附动力学模型进行了分析。结果表明，该阶方程与实验数据拟合较好。通过扫描电镜(SEM)分析了吸附剂表面的作用，扫描电镜图像与吸附测量结果吻合较好。
