Used Filter Cartridges as Potential Adsorbents of Organic Pollutants

The main objective of this study was to assess the usefulness exhausted activated carbon-based filter cartridges for removal organic pollutants from aqueous solutions using example two model pollutants: synthetic dyes with different particle sizes, i.e., methylene blue (MB) and malachite green (MG). In order determine dyes’ adsorption mechanism, effects phase contact time, initial dye concentration, pH, temperature system were investigated. Langmuir Freundlich isotherm models employed analyze experimental data. Additionally, all adsorbents characterized in terms ash content, type porous structure, presence surface functional groups, pH value, iodine number—which is one quality control parameters carbons. Adsorption tests have shown that carbonaceous materials bottle filters jugs can be successfully used liquid phase. maximum sorption capacity adsorbent towards 333.06 mg/g, while case it 308.75 mg/g. For materials, a better fit data achieved than one. It has also been efficiency MB MG decreases increasing system—the best results obtained at 25 °C. A kinetics pseudo-second model.
