Abstract The present work deals with the preparation and characterization of lignin based macromolecular polymeric composites applications thereof. Here is complexed pectin and/ or gellan gum, to form two different green LP LPG. best ratios screened out through evaluation nanoparticle rheology, then confirmed by surface morphology. superior thermal stability proved DSC analysis. reaction groups involving in complexation are FT‐IR spectroscopic where methoxy methyl group interacts hydroxyl gum nanocomposites. reduced particle size charge confirm due interaction between ionizable functional groups. these validated their dye adsorption capacity anti‐microbial properties (after loading silver nanoparticles) which proves multifunctional novel composites. maximum removal efficiency both independent initial concentration. Dye fitted Freundlich isotherms that follow pseudo‐second‐order kinetics. antibacterial study developed loaded unloaded shows wide spectrum activity against E . coli S aureus , higher inhibition gram‐negative organism.
