Аннотация

Heavy metal contamination in wastewater poses a significant environmental and public health risk. Industrial processes such as mining, metal plating, and chemical manufacturing contribute to high concentrations of toxic metals like lead (Pb), cadmium (Cd), mercury (Hg), and chromium (Cr) in water sources. Among various treatment methods, adsorption has emerged as a highly effective and economically viable technique for heavy metal removal. This paper explores different adsorbent materials (e.g., activated carbon, zeolites, biosorbents, and nanomaterials) and their efficiency in heavy metal adsorption. Additionally, factors affecting adsorption capacity, such as pH, temperature, contact time, and adsorbent surface area, are discussed. The study also highlights the potential of novel adsorbents and sustainable approaches to improve adsorption efficiency.
