Efficient Removal of Iodide from Medical Wastewater by D201 Resin
To address the growing volume of iodine-containing radioactive wastewater generated from the use of 131I therapy and limited capacity of decay pools, it is essential to identify an efficient disposal method. This study investigates the treatment of 131I radioactive wastewater using a macroporous strong base anion-exchange resin (D201). A series of batch adsorption experiments were conducted to assess the impact of various factors on the adsorption process, including contact time (0-8 h), temperature (25℃-55℃), pH (3–11), initial iodine concentration (0-3000 mg/L), and presence of competing anions. The results indicate that at a temperature of 25 °C and pH = 7, the adsorption effect of D201 is optimal; the adsorption can reach equilibrium within 2 h; when the initial iodine concentration is 2500 mg/L, the maximum saturated adsorption capacity of the resin can reach 158.02 mg/mL. The adsorption process conforms to the pseudo-second-order kinetic model and the Langmuir isothermal model. Additionally, the resin exhibited a strong preferential selectivity for I−, achieving a removal efficiency of up to 99% in column experiments.
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.
