In this study, white-rot fungus, , collected from an unidentified fallen twig from Pathankot, Punjab, India, was used for biosorption of anionic Congo red and cationic Methylene blue dyes from an aqueous medium. The biosorption efficiency of the live biomass of was investigated to optimize biosorbent dosage, process time, concentrations of dyes, and pH of solutions. The results indicated that is more efficient than other reported bio-adsorbents for Congo red and Methylene blue dyes. The maximum biosorption activity of for Congo red was found at pH 2, and that for Methylene blue was at pH 10, after 24 h of the reaction period. The process followed pseudo-second-order kinetics, which indicated that the interaction of both dyes to the adsorption sites on the surface of was responsive to biosorption. The biosorption process could be well explained by the Langmuir isotherm for both dyes. The maximum monolayer biosorption capacity of for Congo red and Methylene blue was observed to be 54.0 mg/g and 80.6 mg/g, respectively. The seed germination test was carried out, and it was assessed that the toxicity of dyes was reduced up to significant levels. Based on the present experimental findings, it can be concluded that biosorption using the live biomass of can effectively decolorize dye-containing wastewater, thus reducing the hazardous effects of dyes on human beings.

Herein, we propose magnetic nanocomposites as a powerful new catalyst for organic pollutant reduction. Polypyrrole (PPy) was synthesized in situ within the semi-interpenetrating alginate (Alg)/gelatin (Ge) network in presence of α-FeO as encapsulating matrix and inorganic filler, respectively. The polymeric matrix can act as bifunctional agent such as a binder and stabilizer to improve nanocatalyst stability while preserving their catalytic/magnetic performances.

This work developed a novel oxidized hierarchical porous carbon (OHPC) with vesicule-like ultrathin graphitic walls via a method of air oxidation and used as an efficient adsorbent for Congo red (CR) and Malachite green (MG) removal. Results show that the OHPC2 oxidized at 400 °C possesses three-dimensional hierarchical pores with vesicule-like ultrathin graphitic walls. The prepared OHPC2 not only has a large specific surface area of 1020 m g with a high pore volume, but also has abundant oxygen-containing functional groups.

Environmentally friendly nanoporous gels are tailor-designed and employed in the adsorption of toxic organic pollutants in wastewater. To ensure the maximum adsorption of the contaminant molecules by the gels, molecular modeling techniques were used to evaluate the binding affinity between the toxic organic contaminants such as methylene blue (MB) and Congo red (CR) and various biopolymers. To generate nanopores in the matrix of the polymeric gels, salt crystals were used as porogen.
