Effect of preparation conditions of activated carbon prepared from rubber seed coat by KOH activation for removal of Cu (II) from aqueous solution
Rubber seed coat based activated carbon (RSC) was prepared by physiochemical activation consisting of potassium hydroxide (KOH) impregnation plus carbon dioxide (COR2 ) gasification. The R effects of adsorbate initial concentration (10-100 mg/L), contact time, solution temperature (30-60 °C), solution pH (2-6), isotherms and kinetics of the adsorption systems were evaluated through batch adsorption test. Adsorptions of Cu(II) on all the activated carbons prepared were best represented by the pseudosecond-order kinetic model. From the analysis of variance (ANOVA), the significant factors on each experimental design response were identified. The Cu(II) adsorption uptakes increased with increasing initial concentration and contact time.

Abstract

Adsorptions of Cu(II) on all the activated carbons prepared were best represented by the pseudosecond-order kinetic model. From the analysis of variance (ANOVA), the significant factors on each experimental design response were identified. The Cu(II) adsorption uptakes increased with increasing initial concentration and contact time.
