摘要

本研究采用溶剂浸渍树脂(SIR: Amberlite XAD-7浸渍Aliquat-336)在不同操作条件下去除活性蓝-13 (RB-13)染料。进行了批量吸附实验,考察了溶液pH、投加量、动力学、温度、浓度和NaCl盐对吸附剂吸附能力的影响。选择了三种适合动力学数据的动力学模型;伪一阶,二阶和粒子内。扩散。测定RB-13染料的吸附符合准二级动力学。采用傅里叶变换红外光谱(FTIR)、扫描电镜(FE-SEM)和EDX对吸附剂进行了表征。用80% (v/v)乙醇水溶液对溶剂浸渍树脂(SIR)进行再生。

Removal of Reactive Dye Using Solvent Impregnated Resin
In this study, Reactive Blue-13 (RB-13) dye removed by solvent impregnated resin (SIR: Amberlite XAD-7 impregnated with Aliquat-336) at different operation conditions. Batch adsorption studies were dispensed out to gauge the effect of solution pH, dosages, kinetic, temperature, concentration and NaCl salt on the adsorption capacity of the adsorbents. Three kinetic models were chosen to suit the kinetic data; pseudo first order, second order, and intraparticle. diffusion. It had been determined that RB-13 dye adsorption followed pseudo-second-order kinetics. Adsorbent SIR was characterized by Fourier transform infrared spectroscopy (FTIR), Scanning electron microscope (FE-SEM) and EDX. Solvent impregnated resin (SIR) was regenerated with 80% (v/v) ethanol aqueous solution for reuse.
