The synthesized composite consisting of kaolinite halloysites with small clusters of iron oxide on its outer surface was used in batch experiments to adsorb Congo red dye at different temperatures. The adsorption data were fitted to three different isotherms with Langmuir adsorption isotherm best fitting the adsorption data. The maximum adsorption capacity of MK adsorbent was found to be around 45.59 mg/g. Adsorption kinetics data obtained at three different temperatures were fitted to pseudo-first-order and pseudo-second-order models, where the latter model was able to better interpret the obtained kinetics data with a pseudo-second-order rate constant of 8.60 × 10−2 g.mg−1.min−1. Further analysis of the kinetic data revealed that the adsorption mechanism could be explained via intraparticle diffusion model. 2023-08-04T07:47:25Z 2023-08-04T07:47:25Z 2023 Book https://link.springer.com/article/10.1007/s41101-023-00207-x https://dlib.phenikaa-uni.edu.vn/handle/PNK/8687 en application/pdf Springer
