•Graft co-polymer of Gum ghatti with acrylic acid was synthesized.•Polymer degraded successfully with Pseudomonas aeruginosa.•Biodegradation wad evidenced using FT–IR and SEM.•Polymer showed excellent biosorption properties for methylene blue and rhodamine B.•Maximum adsorption efficiency of 909.09 mg/g and 819.67 mg/g was observed for MB and RhB, respectively.
This article reports biosorption properties of Gum ghatti and acrylic acid based graft co-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 Pseudomonas aeruginosa in phosphate buffered saline (PBS) and mineral salt medium (MSM). Gg–cl–PAA degraded faster in PBS (18%) than MSM (15.1%) using P. aeruginosa.
