Kinetic Studies on Heavy Metal Ions Removal by Impregnated Resins Containing Di-(2,4,4-Trymethylpentyl) Phosphinic Acid

Kinetics, equilibrium and thermodynamic study of Cr(VI) sorption into toluidine blue o-impregnated XAD-7 resin beads and its application for the treatment of wastewaters containing Cr(VI)

“…In the application of impregnated support systems in industrial scale equipment using fixed column or fluidized bed technology the knowledge of the kinetics and equilibrium of the removal extraction processes and the operating hydraulic behavior is necessary [24]. The physico-chemical characterization EIR and determination of the kinetic parameters has two objectives:…”

Recovery and Separation of Metal Ions from Aqueous Solutions by Solvent‐Impregnated Resins

“…As the reaction progresses in the particle, the mass balance of counterion A follows Fick's diffusion equation with spherical coordinates [152]. The relationship between reaction time and degree of fractional conversion is given as follows:…”

Sorption potential of impregnated charcoal for removal of heavy metals from phosphoric acid

“…The solvent impregnated materials are characterized by their high binding capacity, selectivity and enhanced mobility of the extractant in the solid surface [7]. Numerous extractants [8][9][10][11][12] were used by this technique such as organophosphorus extractants like di(2-ethyl hexyl phosphoric acid (HDEHP), CYANEX-272, PC-88A; neutral extractants like tri-n-butyl phosphate (TBP) and also basic extractants like tri-n-octylamine (TOA).…”
