Affordable Colorant Removal Using Activated Carbon of Potato Leaves: A Sustainable Alternative

Abstract

The current study shows that using a batch approach to remove colourant (DSDCBS) from water is feasible when using activated carbon obtained from potato leaves as an adsorbent. In order to investigate the effects of parameters, including starting concentration, pH effect, adsorbent dosage, contact time, and temperature, experiments were carried out under various operating conditions. The influence of pH and colourant concentration was shown to be substantial. Langmuir and Freundlich isotherm models were fitted to equilibrium data. The outcomes highlight the applicability of the affordable, locally accessible adsorbent in the speciality area of wastewater treatment and can be used in commercial colourant-enriched effluent.
