Abstract
. In view of thermodynamics, the adsorption process was endothermic and more favorable for CR removal at 45 °C. A reusability study indicated that CYP-PPy could be reused effectively for up to three successive cycles of ad-/de-sorption. Hence, this work provides an alternative scheme for the targeted exploitation of agricultural waste to control dye pollution.
