Sustainable Adsorption of Nickel and Chromium from Aqueous Solutions by Plant-Based Adsorbent
This study introduces a novel and sustainable method for the removal of the heavy metals nickel and chromium from aqueous solutions using modified microcellulose. The modification process utilizes green tea extract and iron sulfate to enhance the surface and structural properties of microcellulose, significantly improving its adsorption performance. X-ray diffraction (XRD) analysis revealed an increase in the crystallinity index from 93 to 98% following modification. Scanning electron microscopy (SEM) showed that the diameter of the modified cellulose fibers reached approximately 6.75 µm. The Brunauer–Emmett–Teller (BET) surface area increased from 1.7 to 2.98 m2/g, while the pore volume nearly doubled compared to unmodified cellulose, indicating enhanced surface characteristics. Particle size distribution analysis showed a reduction in particle size, with a range of 1 to 500 µm. The maximum adsorption capacities were calculated as 8.702 mg/g for chromium and 3.949 mg/g for nickel. The removal efficiencies reached 81% for chromium and 16% for nickel. These results demonstrate the promising potential of green-modified microcellulose as an effective, eco-friendly adsorbent for water treatment applications.
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.
