摘要

本研究首次以聚苯乙烯-二乙烯基苯树脂Amberlyst-15为吸附剂，研究了在合适的吸附条件下，对纺织工业中常用的亚甲基蓝的去除效果。在pH、接触时间、初始染料浓度、吸附剂用量和温度等不同的实验条件下进行了吸附研究。在1.0 g/L吸附剂用量为100 ppm时，Amberlyst-15对亚甲基蓝的最高去除率为98.90%。采用不同的等温线模型分析了吸附等温线数据，并计算了等温线常数。可以看出，所进行的等温线研究与Langmuir模型是一致的。Langmuir等温线方程计算出Amberlyst-15的最大吸附量为178.57 mg/g。采用拟一级、拟二级和颗粒内扩散模型对吸附动力学进行了评价。确定了拟二级动力学模型对Amberlyst-15的适用性。此外，热力学参数的研究和FTIR分析确定了负责吸附的官能团。这些结果表明，Amberlyst-15树脂是一种很有前途的新型吸附剂，可用于去除废水中的亚甲基蓝和其他染料。本研究通过考察Amberlyst-15对亚甲基蓝的去除率，揭示了Amberlyst-15可以作为一种替代的高效吸附剂用于废水中其他染料和污染物的去除。

Polymeric styrene–divinylbenzene resin Amberlyst-15: A novel, smart and alternative adsorbent for the removal of cationic methylene blue dye from aqueous solution

In this study, the removal of methylene blue, which is frequently used in textile industry, from aqueous solution under appropriate adsorption conditions was investigated for the first time using Amberlyst-15, a polymeric styrene–divinylbenzene resin as adsorbent. Adsorption studies were carried out under different experimental conditions such as pH, contact time, initial dye concentration, adsorbent amount and temperature. The highest removal percentage in methylene blue removal studies with Amberlyst-15 was computed as 98.90 % for 100 ppm methylene blue using 1.0 g/L adsorbent. Adsorption isotherm data were analyzed using different isotherm models and isotherm constants were calculated. It was seen that the performed isotherm studies were compatible with the Langmuir model. The maximum adsorption capacity calculated by using the Langmuir isotherm equation was 178.57 mg/g for Amberlyst-15. Adsorption kinetic studies were evaluated with pseudo-first order, pseudo-second order and intraparticle diffusion model. The suitability of pseudo-second order kinetic model was determined for Amberlyst-15. In addition, thermodynamic parameters were investigated and FTIR analysis was performed to determine the functional groups responsible for adsorption. These results suggested that Amberlyst-15 polymeric resin is a promising candidate and new adsorbent for methylene blue and other dyes removal from wastewater. This study is to reveal that Amberlyst-15 can be used as an alternative and efficient sorbent in the removal of other dyes and pollutant species in wastewater via examining the suitability of Amberlyst-15 in the removal of methylene blue.

期刊介绍： The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
