In this work we have prepared a material from a natural waste namely potato peels to clean up contaminated water with a cationic dye i.e. Methylene Blue (MB). Firstly a characterization of the material was carried out in terms of bulk density, ash content, moisture content, pH and electrical conductivity. A parametric study was carried out subsequently and revealed that this adsorbent gives a better adsorption efficiency with respect to BM molecules (Tx = 95.13%) during a contact time of 45 min for a solid mass (4 g), a speed stirring (150 rpm), a solid mass/liquid volume ratio (4 g/250 mL) and an initial dye concentration (10 ppm). The modeling of the adsorption results gave an L-type isotherm with good compatibility with the Langmuir and Freundlich models.enBook chapter
