Abstract:
The aetivated earbon derived from the residue of desilicieation riee husk was used as the potentiaadsorbent for the adsorplion of indigo from the wastewater. E’xperiments were eondueted to study the laetors affecting the adsorption proeess such as the contaet time the dosage of adsorbent and the initial pH. The equilib.rium data agreed well with the Koble-Corrigan isotherm model. The adsorption proeess was spontaneous andendothermie process. The pseudo-first order model, pseudo-seeond order model and intrapartiele model wereused to deseribe the kinetie data. The dynamie data fitted the pseudo-second orler model well which suggestedthat the adsorption might be a chemisorption proeess. Aeeording to the evaluation with the Langmuir equationthe maximum adsorption capacities of indigo dye onto activated carbon was 1. 05 mmol . g-’. lt shows that theaetivated earbon derived from the residue of desilicieation riee husk has a good adsorplion performanee for theindigo dye and can be used as adsorbent to treat the wastewater with high quality.
