TECHNOLOGY FOR PRODUCING BIOABSORBENTS FOR WATER PURIFICATION FROM PLANT RESIDUES GROWING IN TURKMENISTAN

Аннотация

Water scarcity and contamination remain pressing global challenges, particularly in arid and semi-arid regions such as Turkmenistan. One of the promising approaches to addressing this problem is the production of bioabsorbents from locally available plant residues. This study explores the potential of agricultural and forestry by-products—including cotton stalks, wheat straw, and saxaul residues—for the development of eco-friendly bioabsorbents for water purification. The research discusses the physical and chemical modifications required to enhance the adsorption properties of plant-based materials, such as carbonization, activation, and surface functionalization. Furthermore, experimental studies on adsorption capacity for heavy metals, dyes, and organic pollutants are analyzed, highlighting the efficiency and cost-effectiveness of bioabsorbents compared to conventional treatment methods. The integration of bioabsorbent technology into Turkmenistan’s water management strategies not only provides a sustainable solution for environmental protection but also supports the circular economy through the valorization of agricultural residues.
