Developing an Eco-Friendly Adsorbent: Isinglass-Bassorin Cryogel for Safranin O Dye Removal
A novel natural polymer-based cryogel, isinglass-bassorin (IG-BR), was produced with a simplified technique and successfully employed to eliminate safranin O (SO) from the aqueous phase. The cryogel was analyzed using X-ray diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), Fourier-transform infrared spectroscopy (FTIR), and Brunauer–Emmett–Teller (BET) analysis. The Zetta potential measurements revealed a negative surface charge on the IG-BR, making it suitable for removing cationic dyes. An investigation into the adsorption process involved examining the influence of various parameters, including pH, Duration of interaction, Starting dye concentration, quantity of adsorbent, and system temperature. The process of adsorption was further characterized by evaluating its isotherms, kinetics, and thermodynamics. The maximum sorption capacity of the IG-BR cryogel reached 208.76 mg/g. Experimental findings revealed that the adsorption data for the IG-BR cryogel were effectively fitted to pseudo-first-order kinetics and the Langmuir isotherm. Furthermore, cryogel exhibited commendable stability, maintaining a high level of adsorption capacity throughout five regeneration cycles.
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.
