| Popis: | Nowadays, water pollution caused by diverse poisonous compounds, particularly hydroxy aromatic compounds and their derivatives, has become a prominent environmental issue because of the possible toxicity to human beings. This research adopted an adsorptive method to remove catechol using a water-stable hydroxyl-functionalized terbium–organic framework for the first time. The as-synthesized new metal–organic framework (Tb–MOF) shows favorable thermostability and water stability based on results of thermogravimetric analyses, water vapor sorption, and powder X-ray diffraction. Along the c axis, Tb–MOF has a three-dimensional framework with channels of 8.4 × 8.1 A2 as well as high adsorption capacity with the maximal adsorption capacities of 260 mg/g for catechol than that of any reported adsorbent so far. Thermodynamics, adsorption kinetics, effects of pH, and effects of temperature were investigated in a batch reactor. The remarkably high adsorption capacity of Tb–MOF could be explained by the appropriate ... |
