An acid‐thermally modified Merremia vitifolia biosorbent (ATMVB) was used for the removal of 2,4‐dichlorophenoxyacetic acid (2,4‐D) from its aqueous solution. The characteristics of ATMVB were found to be superior to that of the unmodified Merremia vitifolia biosorbent (UMMVB). Batch biosorption experimental data under the optimal treatment conditions for ATMVB best fitted to a pseudo‐first‐order kinetics model and Langmuir adsorption isotherm with a defined maximum biosorption capacity. The mechanism of biosorption was explained with two intraparticle diffusion models, namely, Weber and Boyd. The biosorption is exothermic as per the thermodynamic studies. The ATMVB can be considered as a potential biosorbent for the removal of 2,4‐D from its aqueous solution.

酸热修饰的玻璃体足叶酸去除2,4-二氯苯氧基乙酸

酸热改性金钟vitifolia生物吸附剂（ATMVB）用于从其水溶液中除去2,4-二氯苯氧基乙酸（2,4-d）。发现ATMVB的特性要优于未修饰的金钟vitifolia生物吸附剂（UMMVB）。在最佳处理条件下，针对ATMVB的分批生物吸附实验数据最适合拟一级动力学模型和具有定义的最大生物吸附容量的Langmuir吸附等温线。用两个粒子内扩散模型，即韦伯和博伊德，解释了生物吸附的机理。根据热力学研究，生物吸附是放热的。ATMVB可被视为潜在的生物吸附剂，可从其水溶液中去除2,4‐D。
