摘要: This paper describes studies of functionalized mesoporous silica employed as adsorbent for Mn(II) from aqueous solutions. The surface area MCM-41 and diethylenetriamine functionalized-MCM-41 used in this study were 760 318 m(2) g(-1) (N2 adsorption). A strong dependence on pH the adsorption capacity best results obtained at 6.5-7. onto followed pseudo-second-order kinetic model highest reaction rate 0.324 min(-1) was observed low initial concentration 10 ppm. equilibrium data showed excellent correlation with Langmuir isotherm maximum reached 88.9 mg/g DETA-MCM-41 indicating that occurs a homogeneous by monolayer sorption without interaction between adsorbed ions. These contribute to understanding mechanisms involved provide some practical clues improve efficiency (uptake kinetics)
