摘要

本研究调查了椰壳衍生活性炭去除水溶液中三氯生(TCS)的功效。实验结果表明,椰壳衍生活性炭在去除水中的三氯生(TCS)方面具有令人印象深刻的功效。统计分析强调了搅拌在提高吸附效率方面的重要作用,增加搅拌可提高污染物去除率。很快就能达到平衡,去除率超过 85%。动力学分析表明,吸附动力学速度很快,主要遵循伪二阶模型。此外,颗粒内扩散分析深入揭示了三氯氢硅在活性炭孔隙内的扩散情况,突出了其对溶质浓度的依赖性。这些发现强调了椰壳衍生活性碳作为一种可行的解决方案来减轻水源中的 TCS 污染的潜力,有助于开发有效的水处理策略。

Kinetic modeling and optimization of triclosan adsorption onto coconut shell activated carbon
This study investigates the efficacy of activated carbon derived from coconut shells for the removal of Triclosan (TCS) from aqueous solutions. Experimental results demonstrate the impressive efficiency of coconut shell-derived activated carbon in eliminating TCS from water. Statistical analysis underscores the significant role of agitation in enhancing adsorption efficiency, with increased agitation leading to higher contaminant removal rates. Equilibrium is rapidly achieved, with removal efficiencies exceeding 85 %. Kinetic analysis reveals rapid adsorption kinetics, predominantly following the pseudo-second-order model. Additionally, intraparticle diffusion analyses provide insights into TCS diffusion within activated carbon pores, highlighting its dependence on solute concentration. These findings underscore the potential of coconut shell-derived activated carbon as a viable solution for mitigating TCS contamination in water sources, contributing to the development of effective water treatment strategies.
