Maximum adsorption capacity
WebBonding energies in adsorption range from about 10 to 70 kJ/mol, much lower than typical covalent bond energies of 200 to 500 kJ/mol. The adsorp- tion bonding energy is high enough for adsorption to occur, yet low enough to allow the adsorbent to be regenerated by removing the adsorbed molecules. Equilibrium considerations WebIn the GO/Fe 3 O 4 adsorbed fulvic acid, the sorption capacity for Cu(II) was enhanced at pH 5.3, and the sorption capacity for fulvic acid was also enhanced after Cu(II) sorption on GO/Fe 3 O 4. The experimental data was modeled with Langmuir and Freundlich isotherm models and fitted well to the Langmuir isotherm equation with a maximum …
