Abstract

This is the first report on improving activated carbon fabric (ACF) as an adsorbent for the removal of heavy metals. Magnetic-activated carbon fabric (MACF) was synthesized from waste cotton fabric using a sonosynthesis method with iron salt for removing Cu²⁺ and Cd²⁺ ions from aqueous solutions. MACFs were characterized with BET, FT-IR, and VSM methods. Optimal conditions for ions removal were pH = 4 for 50 mg L⁻¹ initial concentration of Cu²⁺ and Cd²⁺ with 1.5 g L⁻¹ MACF at 20 ± 1 °C and 200 rpm for 1 h. The equilibrium data of adsorption thermodynamics, isotherms, and kinetics of Cu²⁺ and Cd²⁺ using MACF was investigated. The highest regression values of 0.9998 and 0.9750 were obtained by the Langmuir model among other models for adsorption isotherm using MAFC for Cu²⁺ and Cd²⁺ respectively. MACF revealed a higher metal removal of 99.2% for Cu²⁺ and 94.9% for Cd²⁺ for both ions compared to 32% for Cu²⁺ and 28% for Cd²⁺ using ACF. The results indicate that MACF shows superior performance/cost-effective in removing heavy metal ions compared to granules and powder-activated carbons, which can be easily prepared in different dimensions and removed from the filter/environment, making it a promising alternative for applications requiring enhanced heavy/toxic metal removal from any 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.
