Poly (acrylonitrile) chains were grafted onto the cellulosic backbone and biosorbent cellulose-g-acrylonitrile (Cell-g-AN) was used for the removal of organic pollutants such as methyl red (MR), rhodamine 6G (Rh 6G) and methylene blue (MB) dyes from polluted water. Batch adsorption experiments were done to improve operating parameters. We examined the relationship between dye adsorption and pH, temperature, and contact time. The Cell-g-AN’s high grafting percentage value and nitrile group of AN, which under ideal pH conditions give extra binding sites, were found to be related to the material's adsorption capability for a variety of dyes. Under optimized circumstances, cellulose demonstrated maximal dye-removing capacities of 87.64%, 88.49%, and 63.08% for Rh 6G, MB, and MR dyes, respectively.

To address the need for efficient removal of the toxic dye methylene blue (MB) from water, a composite material was synthesized using biomass derived from banana peels and magnesium oxide (MgO) nanoparticles. Key operational parameters—including pH, contact time, composite dosage, and initial MB concentration—were systematically optimized to maximize MB adsorption. The composite was thoroughly characterized using advanced analytical techniques such as Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD), and Brunauer–Emmett–Teller (BET) surface area analysis. The optimal conditions for MB adsorption were initially determined using the one-factor-at-a-time (OFAT) method and later confirmed through response surface methodology (RSM). The optimal parameters were found to be a pH of 7.6, a contact time of 30 min, an initial MB concentration of 80 mg/L, and a composite dosage of 20 mg. Under these conditions, the composite achieved an optimal MB removal efficiency of 96.45%. Kinetic analysis showed that the adsorption process followed a pseudo-second-order model, while equilibrium data aligned well with the Freundlich model. The composite exhibited a maximum adsorption capacity of MB was 76 mg/g of adsorbent. The adsorption mechanism involved chemisorption followed by physisorption, with electrostatic interactions playing a significant role.

The reduction of Bio-S-PdFe was mediated and accelerated by hydrogen gas (Bio-H₂) generated by the microbes during fermentation. Biogenic Bio-S-PdFe was used for PNP biodegradation, with the removal conditions optimized using RSM.
