Modified Wheat Starch Granules for Ibuprofen Adsorption in Aqueous Solution
Cross-linked cationic wheat starches (CLCS) of different degree of substitution (DS) of quaternary ammonium groups were synthesized with or without the addition of CaO and used for ibuprofen (IB) adsorption in an aqueous solution. The equilibrium adsorption of IB onto modified starch granules was investigated. The parameters of the Dubinin-Radushkevich, Fowler-Guggenheim, Freundlich, and Langmuir adsorption models were calculated and revealed that the driving forces of adsorption were electrostatic interactions between quaternary ammonium groups of modified starch and carboxylate groups of IB. The adsorption process was best described by employing the Langmuir isotherm model and the highest adsorption capacity for IB uptake equal to 550 mg/g was achieved by using CLCS with DS of quaternary ammonium groups of 0.51. The addition of CaO to the synthesis mixture improved the adsorption properties of CLCS granules and allowed to generate a potential sorbent for the removal of IB from the aqueous solution.
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.
