以板栗壳为吸附剂，研究了板栗壳对活性艳红K-2G的吸附性能。采用间歇吸附实验研究了溶液初始pH值、吸附剂投加量、染料初始浓度和温度对吸附的影响。结果表明，强酸性条件有利于吸附过程的进行，最佳pH值为1.0。Freundlich等温线适合描述实验数据。板栗壳对RBR的吸附符合准二级动力学模型。吸附速率主要受外部传质控制。热力学研究表明，吸附过程的自发和放热性质。红外光谱分析表明，板栗壳表面的胺基、羟基和酚类化合物等官能团可能是吸附RBR的活性结合位点。
Chestnut shell, an agricultural residue, was used as a low-cost adsorbent to remove Reactive Brilliant Red K-2G (RBR) from aqueous solution. Batch adsorption experiments were conducted to study the effects of initial solution pH value, adsorbent dosage, initial dye concentration and temperature on the adsorption. It was proved that strong acidic condition was favorable for the adsorption process and the optimal pH value was 1.0. Freundlich isotherm was appropriate for describing the experimental data. The kinetics study revealed that the adsorption of RBR onto chestnut shell followed the pseudo-second order model well. The external mass transfer mainly governed the adsorption rate. Thermodynamic studies demonstrated the spontaneous and exothermic natures of the adsorption process. The FTIR analysis indicated that functional groups such as amine, hydroxyl and phenolic compounds on the chestnut shell may be the active binding sites for the adsorption of RBR.
