摘要: The adsorption behavior, isotherms, kinetics and thermodynamics of molybdenum(VI) on modified rice husk (RH) corn straw (CS) in an aquatic environment were investigated. CS gel has shown a high affinity for Mo(VI) selectivity toward its compared to Re(VII) other base metals like Cu(II), Pb(II), Fe(III), Zn(II), Mn(II) Ni(II). Adsorption mechanism onto the gels could be supposed ion exchange and/or H-banding depending solution pH. equilibrium both RH was best described by Langmuir model. A kinetic study molybdenum confirmed that it endothermic process, which further validated thermodynamic data. Reutilization up six adsorption-elution cycles column-mode operation with no damage gels, packed column. result also provides new approach removal (approximately 99.50 %) from Mo-containing surface water using straw.
