摘要: AbstractThe present paper assesses the adsorption capability of rice husk ash (RHA) to adsorb catechol (C) along with phenol (P) and resorcinol (R) individually simultaneously from aqueous solution in both single binary solutions using batch experiments. Equilibrium isotherm data were collected at 30°C by carrying out experimental runs for 24 h contact time pre-optimized RHA dosage 20 mg/L initial concentration variation individual components range 50–500 mg/L. The equilibrium component fitted three models, namely Langmuir, Freundlich Redlich–Peterson. catechol–phenol, catechol–resorcinol parameter evaluated various multi-component models. Extended Langmuir model which assumes overlapping sites different adsorbates better represented bot...
