In this study, a sustainable adsorbent (hereinafter, CHI/FL-OXA) generated from chitosan and activated Fig (Ficus carica L.) leaves using oxalic acid was created for effective organic dye (crystal violet, CV) adsorption. Box-Behnken Design (BBD) helped to accomplish the modeling and optimization of the adsorption variables comprising A: CHI/FL-OXA dose (0.02-0.08 g/L), B: pH (4-10), and C: time (10-40 min). The best variables for maximal CV uptake (93.1%) were as follows: CHI/FL-OXA dose = 0.064 g/L; pH ∼ 9.2; contact duration = 27.6 min. Agreements with pseudo-first-order and Freundlich models were shown by the experimental results of CV adsorption by CHI/FL-OXA. The intraparticle diffusion plots reveal three linear stages, indicating a multi-step adsorption process where initial dye transport is followed by intraparticle diffusion and surface adsorption, with the non-zero intercept (C ≠ 0) confirming that intraparticle diffusion is not the sole rate-controlling mechanism. The CHI/FL-OXA biomaterial, with an adsorption capacity of 375.72 mg/g, exhibited strong potential for adsorbing cationic dyes like CV dye. Adsorption of CV cationic dye on the CHI/FL-OXA enfolds numerous interactions, including electrostatic forces, Yoshida H-bonding, n-π, and H-bonding.

The thermochemical conversion process was carried out by using microwave irradiation assisted ZnCl2 activation for 15 min with 800 W. The physicochemical properties of RSPSFSP-AC were evaluated using several analytical techniques, including pHpzc, BET, FTIR, and SEM-EDX analysis. The adsorptive property of RSPSFSP-AC for FB removal was evaluated and optimized by using the Box-Behnken design (BBD) and desirability function. The desirability function optimal conditions for FB removal (92.8%) were found to be 0.09 g/100 mL of RSPSFSP-AC dosage and 9.2 solution pH. The adsorption kinetic isotherm of the FB dye was explained by the pseudo-second order (PSO) model and Langmuir isotherm model respectively. The maximum adsorption capacity (qmax) of RSPSFSP-AC for the FB dye was found to be 147.7 mg/g. The adsorption of the FB dye onto the RSPSFSP-AC surface can be explained by several possible interactions including π-π stacking, electrostatic forces, pore filling, and hydrogen bonding.

The process effectively treated 500 mL of synthetic wastewater containing 100 ppm zinc ion and the process could be enhanced to achieve the removal efficiency of 90% by adjusting the solution pH to slightly acidic (pH 5) and increasing the mass of duckweed to its saturation point (20 g). Excessive zinc intake by duckweed led to chlorophyll reduction, negatively impacting the duckweed growth rate. Scanning electron microscopy (SEM) analysis revealed that the duckweed fronds' surface became uneven after the treatment, with the irregular small particles attached due to cellular damage. The energy dispersive X-ray (EDX) analysis confirmed the successful uptake and accumulation of zinc in the duckweed cells from the synthetic wastewater.
