Enhanced adsorption of methyl orange from aqueous solutions using a functionalized styrene-divinylbenzene copolymer
The adsorption efficiency of the styrene-divinylbenzene copolymer functionalized with carboxylic acid groups (SDVBF) was investigated for methyl orange (MO) removal from aqueous solutions. The effects of contact time and of the initial concentration on the amount of MO adsorbed were studied. The kin...

| Tartalmi kivonat: | The adsorption efficiency of the styrene-divinylbenzene copolymer functionalized with carboxylic acid groups (SDVBF) was investigated for methyl orange (MO) removal from aqueous solutions. The effects of contact time and of the initial concentration on the amount of MO adsorbed were studied. The kinetics of MO adsorption onto SDVBF copolymer was described by the pseudo-second order model. It was demonstrated that Redlich-Peterson model is the most suitable to describe the adsorption of MO onto SDVBF copolymer. The maximum adsorption capacity of the SDVBF adsorbent, resulted from the Langmuir isotherm was 53.12 mg g-1. |
