Potential of Rice Husk and Rice Husk Ash for Phenol Removal in Aqueous Systems
Open accessAbstract
The potential of rice husk and rice husk ash for phenol adsorption from aqueous solution was studied.Batch kinetics and isotherm studies were carried out under varying experimental conditions of contact time, phenol concentration, adsorbent dose and pH.Adsorption equilibrium of rice husk and rice husk ash was reached within 6 hours for phenolic concentration 150-500 µg/L and 3 hours for phenol concentration 500-1300 µg/L, respectively.Kinetics of adsorption obeyed a firstorder rate equation.The adsorption of phenol increases with increasing the solution pH value.The suitability of the Freundlich and Langmuir adsorption models of the equilibrium data was investigated for each phenol-sorbent system.The results showed that the equilibrium data for all the phenol-sorbent systems fitted the Freundlich model best within the concentration range studied.A comparative study showed that rice husk ash is very effective than rice husk for phenol removal.The studies showed that the rice husk ash can be used as an efficient adsorbent material for removal of phenolic from water and wastewater.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
