Summary, etc. <span style="&quot;font-size: 11.0pt;" lang="&quot;EN-GB&quot;">Adsorption of basic dye Crystal Violet (CV) from aqueous solution by two low cost adsorbents Ground Nut shell powder (GNSP) and Ground nut shell ash (GNSA) has been investigated through batch mode adsorption process. The study involves the removal of CV using operational parameters; initial concentration (100-600 mg/L), different contact time, adsorbent dose (0.1-0.5 g/100mL) and <em>p</em>H (3-10). It has been found that percentage removal of dye improve with reduction in original concentration, intensification in time of contact and adsorbent dose. Basic <em>p</em>H of the dye solution show better adsorption capacity as compared to acidic dye solution. FTIR analysis reveals the presence of favourable alcoholic and carboxylic groups on the surface of the adsorbent. SEM analyses show irregular morphology with particles in micrometer range. Langmuir isotherm fit better than Freundlich adsorption isotherm and to Lagergren second order kinetic model fitted better than first order for both the adsorbents. Results show that GNSP performed better than GNSA. It can be concluded from the study that GNSP can be used as a low cost adsorbent.</span>
