polymers for the adsorption of methylene blue (MB) and rhodamine B (RhB). Gg–cl–PAA
removed 99% MB and 98% RhB from the respective dye solutions. Adsorption isotherm
followed Langmuir isotherm with maximum adsorption capacity of 909.09 mg/g (MB) and
819.67 mg/g (RhB). Both the dyes followed pseudo second order rate equation. Eco-
friendliness of Gg–cl–PAA was studied by assessing its susceptibility to biodegradation by …
