Using quail eggshell to treat methylene blue in aqueous solution

In study "Using quail eggshell to treat methylene blue in aqueous solution", the raw quail eggshell powder (RQEP) was utilized as a cheap and environmentally friendly adsorbent to remove methylene blue (MB) from aqueous media under different conditions. The morphology of the prepared adsorbent was determined by scanning electron microscopy. The Langmuir and Freundlich isotherm models were used to model the adsorption data. The obtained results showed that the adsorption of MB on RQEP was well-fitted with the Freundlich model.
