Abstract

The present study reported the preparation of solid phases from various available and cheap natural sources represented by activated carbon to remove the polluting dye Congo Red (CR). Activated carbon derived from the leaves of the Consocarpus plant (C/AC) and Ziziphus Spina-Christi plant (Z/AC) and Myrtus plant (M/AC) by chemical activation. The solid phases were diagnosed and examined using FTIR, FESE, and XRD. The results of the study indicated that the best amount for the solid phase was 0.25 g for the three solid phases used against dye, the optimal concentration of the CR was 100 mg L-1, and the optimum acidity function was equal to 5 with a volume of 25 mL, as the optimization experiments indicated that the best flow rate of the eluting solution was equal to 0.5 ml min-1. The elution processes were carried out using several solvents different in polarity and it was found that 8 mL of DMSO achieved the best percentage of recovery (%R). Also, the adsorption capacity based on the optimal conditions that were obtained by applying Langmuir and Freundlich isotherm models, and qmax, according to the Langmuir model, was (21.74, 23.53, 22.17) mg g-1 for (Z/AC), (C/AC), and (M/AC) adsorbents, respectively.
作为固相活性炭的一种高效廉价的来源,用于从水溶液中提取和去除刚果红
本研究报道了以活性炭为代表的多种廉价天然原料制备固相以去除污染染料刚果红(CR)。采用化学活化法,从果壳植物(C/AC)、紫皮植物(Z/AC)和桃金娘植物(M/AC)的叶片中提取活性炭。采用FTIR、FESE和XRD对固相进行了诊断和检测。研究结果表明,三种固相对染料的最佳固相用量为0.25 g, CR的最佳浓度为100 mg L-1,最佳酸度函数为5,体积为25 mL,优化实验表明,洗脱液的最佳流速为0.5 mL min-1。用不同极性的溶剂进行了洗脱过程,发现8ml DMSO的回收率最高(%R)。采用Langmuir和Freundlich等温线模型得到的最佳吸附条件下,(Z/AC)、(C/AC)和(M/AC)吸附剂的吸附量qmax分别为(21.74、23.53、22.17)mg g-1。
