Abstract
To remove methylene blue dye from wastewater, chemically modified rice husk has been used in the laboratory scale that comprises batch study leading to adsorption kinetics rate constants and maximum adsorption capacities. It has been observed that almost 95–99% of dye can be removed from the solution using treated rice husk. Langmuir adsorption isotherm, Freundlich isotherm model and Temkin model have been used to describe the distribution of dye between the liquid and solid phases in batch studies and it has been found that Langmuir isotherm represents the phenomenon better than other isotherm models. Due to low cost of rice husk this may be an effective material in the treatment of waste water containing dye and this material is biodegradable and eco-friendly.
