Investigating Humic Acid Adsorption from Aqueous Solution using UiO-66 Functionalized with Amine Group

Background: Natural Organic Matters (NOMs) are pollutants that exist in many drinking water resources, cause problems treatment processes, and have adverse effects on human health. For this reason, these substances must be removed from via a proper method. Metal Frameworks (MOFs) novel adsorbents been widely considered recent years. In study, Uio-66 functionalized with NH2 was synthesized applied for humic acid adsorption (as natural organic matter) removal water. Materials Methods: The present study conducted batch reactor laboratory scale. Firstly, the characteristics of adsorbent were investigated. Then, effect different parameters such as pH, dosage, initial concentration process also Additionally, isotherms kinetics Uio-66-NH2 determined. data analysis comparisons using linear regression determination coefficient. Results: confirmed structure properties fabricated nanoparticles. surface area 673.4 m2/g. results showed optimal pH range 5 to 7, dose 0.8 g/L, maximum 2.2 mg/g adsorbent. Conclusion: Based findings research, isotherm accordance Langmuir model its followed pseudo-second-order kinetic model. current revealed by optimization condition, can used matter removal.
