Cotton is a widely cultivated cash crop and represents one of the most significant raw materials for textiles on global scale. The rapid development cotton industry has resulted in production substantial amounts husks, which are frequently underutilized or discarded. This study utilizes agricultural waste, specifically shells, as precursor biochar, subsequently carbonized nitrogen-doped with ruthenium oxide to synthesize an innovative composite material known RuO2-NC. An electrochemical sensor was developed using this detect heavy metals, particularly lead copper ions. results demonstrate that can accurately quantify concentrations ions across wide linear range, exhibiting exceptional sensitivity. Furthermore, tested samples from Viola tianshanica Maxim (Violaceae) collected Xinjiang Uygur Autonomous Region (XUAR) China, showing commendable accuracy approach promotes eco-friendly recycling waste while offering advantages such straightforward operation reduced costs, thereby presenting promising prospects practical applications.
