Title A name given to the resource Synergistic Effect of Chemical and Physical Treatments on Azolla pinnata for Cadmium Ions Removal from Synthetic Wastewater Systems Subject The topic of the resource Azolla pinnata; cadmium chelation; chemi-cal and physical modifications; phytoremediation; surface properties Description An account of the resource Azolla pinnata, an aquatic fern has been utilized as an effective biofiltering and ad-sorbent agent to complement many convention-al treatment methods for the removal of environmental pollutants. This study is designed to develop an effective regime to treat metal pollutants of industrial and urban waste discharge using a novel strategy involving Azolla pinnata. In the present study, cell surface modification by physical treatments that include heating (muffle furnace), and mechanical waves (ultrasonication) and chemical treatments as sulphuric acid and ethanol were employed to enhance the adsorption of metal pollutants. Factors such as biosorbent dose, contact time, initial metal ion concentration, temperature, and solution pH were optimised in batch mode. The point of zero charge of the adsorbent was determined to be at 5.85 pH. The results of surface morphology, elemental analysis, crystallinity, recorded through SEM, FTIR and XRD confirmed the ad-sorptive properties in both modified and unmod-ified biomass. The intensity peaks linked to O-H, C-H, C-N, N-H and C=O stretching bands was intense in the treated A. pinnata groups indicat-ing the induction of the active groups. Out of the two chemical pre-treatments, the batch ad-sorption experiment with ethanol found to che-late Cd+2 metal ions to a higher extent (94.36%) in contrast to the results obtained from H2SO4 treated biomass. Whereas, the physical treat-ments exhibited the strong adsorption (83.28 and 96.920.55%) for ultrasonicated and muf-fle furnace pre-treated biomass respectively for the dosage of 0.25g. The adsorption efficiency of physically modified sorbent revealed the cent percent removal of Cd+2 ions from the aqueous phase with the dosage of 1.0g in 15min of con-tact time which is due to the incorporation of new binding sites. Moreover, these results proved that the highest rate of cadmium adsorption onto A. pinnata is in result of the modifications caused onto surface structure, porosity and the addition of functional groups on the surface of the treated biomass. 2024, Curr.
