On July 25, 2022, Zhang, Xinling; Yuan, Ning; Xu, Shuo; Li, Yi; Wang, Qibao published an article.Formula: C13H10O3 The title of the article was Efficient adsorptive elimination of organic pollutants from aqueous solutions on ZIF-8/MWCNTs-COOH nanoadsorbents: Adsorption kinetics, isotherms, and thermodynamic study. And the article contained the following:
The removal of organic pollutants was examined by new zeolitic imidazolate framework-8/carboxyl-functionalized multi-walled carbon nanotubes (ZIF-8/MWCNTs-COOH) nanoadsorbents, which were prepared via controlling the reaction sequence of MWCNTs-COOH with the precursors of ZIF-8. Structural morphol. and chem. composition characterizations confirmed the successful preparation of ZIF-8/MWCNTs-COOH nanoadsorbents. The obtained samples manifested a preferable adsorption capacity for Congo red with the maximum adsorption capacity of 1185.58 mg g-1 with an adsorption removal rate of 97.93% at equilibrium adsorption. Further analyses indicated that the adsorption process conformed to the pseudo-second-order kinetic model and Langmuir adsorption isotherm. The thermodn. analyses were depicted as endothermic, entropy-increasing, and spontaneous. The effects of pH value, interfering ions, and dosage on the adsorption properties were systematically explored. The nanoadsorbent can be expediently reused for eight cycles without a prominent reduction in adsorption activity. The improved performance and high reusability can be ascribed to the increasing sp. surface, the presence of electrostatic interaction, hydrogen bonding, and π-π interaction between ZIF-8/MWCNTs-COOH and organic mols. In addition, the prepared composites also showed a better adsorption performance for tetracycline with the equilibrium adsorption capacity of 471.22 mg g-1 compared to pure ZIF-8 and MWCNTs-COOH. The experimental process involved the reaction of Phenyl Salicylate(cas: 118-55-8).Formula: C13H10O3
