Expired Medicine-Derived Wonder Scavenger for The Removal of Harmful Dyes With No Hazardous Footprint
Exorbitant dye contamination in water augments health quandaries in living beings. Besides, expired medicines induce secondary hazards owing to mismanaged, rampant disposal in environments. To quench the dual problem, the waste-to-best protocol was exercised maneuvering the conversion of an expired medicine ‘Oflofrenz-OZ’ to activated carbon (OAC) followed by extraordinary ultrafast scavenging of recalcitrant bromothymol blue (BTB), and crocein orange (CO) from water. The material is well characterized using powder XRD, FESEM-EDX, pHZPC, and BET surface area. FESEM exhibits a highly porous morphology, evenly decorated, thereby offering a favorable dye-hosting platform. Outstanding adsorption capacities for BTB and CO (362.318 and 1008.089 mg/g) are powered by ultrafast kinetics, obeying the Langmuir monolayer model (R2 = 0.999). Mild alkali-assisted regeneration revives the material by up to 50%, enabling three-cycle reuse. OAC performs well with simulated wastewater from tube-well, tap, and reverse osmosis systems, which synergistically advocates field applicability. The long-hankered disposal problem of dye-loaded spent material has been addressed by converting it to a second-generation carbon-based adsorbent with an 80% yield. Compared with analogous materials, the present material is a clear winner, thanks to its extraordinary adsorption efficacy, economic viability, and zero footprints.
期刊介绍：
Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments.
Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation.
Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
