Wide-Spectrum Dye Adsorption Performance of Alginic Acid Carbon Aerogel
Multifunctional adsorbents are significant for the treatment of water-soluble dyes in contaminated aquatic systems and oily dyes in colored organic effluents. However, the existing adsorbent for both water-soluble and oil-soluble dyes is rare and the cleanup effect is not ideal. In this study, alginic acid carbon aerogel (AACA) as an effective wide-spectrum adsorbent was prepared through wet-spinning, ion-exchanging, drying, and high-temperature carbonization. AACA obtained a specific surface area of 1046.0 m2 g−1 and a mean pore size of 2.82 nm. The adsorption capacities of AACA for methylene blue (cationic dye), methyl orange (anion dye), and oil red O (oil-soluble dye) were 493.5, 389.5, and 244.2 mg g−1, respectively, which were improved in comparison with those of previously reported calcium alginate and ferric alginate carbon aerogels. The adsorption kinetics of AACA for the three dyes were fit for the pseudo-second-order kinetic model and the adsorption isotherms could be explained by the Langmuir model. ACCA revealed good adsorption performance for other eleven different sorts of dyes and binary dye systems. The adsorption mechanism was mainly confirmed to be π–π interactions.
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.
