Mono-ethylene glycol (MEG), used in the oil and gas industries as a gas hydrate inhibitor, is a hazardous chemical present in wastewater from those processes. Metal-organic frameworks (MOFs) (modified UiO-66* and UiO-66-2OH) were used for the effective removal of MEG waste from effluents of distillation columns (MEG recovery units). Batch contact adsorption method was used to study the adsorption behavior toward these types of MOFs. Adsorption experiments showed that these MOFs had very high affinity toward MEG Significant adsorption capacity was demonstrated on UiO-66-2OH and modified UiO-66 at 1000 mg.g(-1) and 800 mg g(-1) respectively. The adsorption kinetics were fitted to a pseudo first-order model UiO-66-2OH showed a higher adsorption capacity due to the presence of hydroxyl groups in its structure. A Langmuir model gave the best fitting for isotherm of experimental data at pH = 7. (C) 2018 Elsevier Inc. All rights reserved.
