Biochar has emerged as a promising eco-friendly material for addressing chemical oxygen demand (COD) in wastewater treatment, offering sustainable alternatives to conventional purification methods. This review systematically examines its multifunctional roles through physicochemical characteristics including developed surface area, porous structure, and functional groups that collectively enable effective COD removal via adsorption, catalytic degradation, microbial interactions. The oxidation-reduction reactions facilitated by persistent free radicals oxygen-containing demonstrate particular effectiveness decomposing complex organic pollutants. Recent advances highlight optimization strategies precursor selection, pyrolysis condition modification, hybrid systems combining biochar with advanced oxidation processes or biological treatments, which synergistically enhance treatment efficiency operational stability. Practical applications reveal biochar's adaptability across various types, though performance variations depend on feedstock sources, activation methods, reactor configurations. Environmental sustainability assessments indicate reduced secondary pollution risks compared traditional potential resource recovery spent utilization soil amendment. Current challenges center long-term stability continuous flow systems, cost-effective regeneration techniques, standardized evaluation protocols industrial-scale implementation. Future research directions emphasize biochar-based composite development, artificial intelligence-assisted process optimization, life-cycle assessment frameworks advance circular economy water control.

Enzymes play a vital role in various industrial sectors and are essential components of many products. Hybrid enzyme-polymeric capsules were developed using polysulfone-activated carbon as scaffolds. The with an average diameter 2.55 mm fabricated by applying phase inversion precipitation method. An increase the amount immobilized enzymes was observed growth activated polysulfone matrix. Enzyme immobilization confirmed Bradford method, while Viscozyme® L activity carboxymethyl cellulose hydrolysis to glucose measured Reducing Sugar DNS recycling hybrid L-polysulfone/activated capsules, their reuse for subsequent investigated demonstrated repeatability results.
