Enhanced adsorption of ketoprofen and 2,4-dichlorophenoxyactic acid on Physalis peruviana fruit residue functionalized with H2SO4: Adsorption properties and statistical physics modeling

• The functionalization of Physalis peruviana biomass with H 2 SO 4 is reported. surface chemistry this modified was characterized. Adsorption ketoprofen and 2,2-dichlorophenoxyactic acid studied. Application physical model on adsorption isotherms. In research, a its application in the particular, properties were improved through sulfuric treatment to enhance removal performance organic molecules. Surface also Experimental isotherms these pollutants determined at 298 – 328 K pH 2. A multilayer statistical physics used data modeling analyze corresponding mechanism. Results showed that endothermic multi-molecular process where molecular aggregation could be expected. On other hand, functionalized multi-anchoring. energies (?E 1 ) varied from 4.13 5.53 kJ/mol for KTP 7.54 7.96 2,4-D herbicide. These results forces involved molecules because < 40 kJ/mol.
