Unveiling Impact of Polyamide Microplastics on Ceftiofur Sodium Migration in Porous Media: Experimental and Modeling Insights
Polyamide (PA) and cephalosporin, specifically ceftiofur sodium (CTFS), are commonly found in soil environments. The impact of microplastics on the transport of cephalosporin cannot be disregarded due to their surface hydrophobicity and large specific surface area. This study investigates the influence of PA microplastics on the transport of CTFS in porous media through a combination of experimental and numerical modeling approaches, investigating how environmental factors affect CTFS transport. The adsorption of CTFS on PA is inversely correlated with the increase in ionic strength, specifically with the presence of Na+, Ca2+ and Ba2+ ions. This suggests a significant impact of ionic strength on the adsorption process. Experimental findings indicate that higher mass fractions of PA result in greater retention of CTFS within the columns. Conversely, elevated flow velocities and initial CTFS concentrations facilitate the migration of CTFS in PA-silica sand (SS) mixed porous media. Additionally, the migration of CTFS is modeled using the advection–dispersion equation (ADE) with first-order kinetics, yielding a coefficient of determination (R2) exceeding 0.95. Subsequently, the correlation between kinetic parameters of CTFS and various environmental factors such as PA%, flow velocity, initial concentration, and ionic types and strengths is determined. These results contribute to a deeper understanding of the environmental interactions between microplastic particles and antibiotics within porous media, and offer a scientific foundation for precise forecasting and evaluation of the environmental hazards posed by microplastic contamination in soil-groundwater system.
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.
