Synthesis of chemically regenerable magnetic bio-nanocomposite adsorbents derived from agricultural waste for sustainable remediation of Pb(II), Cd(II), and Cr(VI) in contaminated water systems in the Niger delta
Heavy metal contamination poses a critical threat to water security in oil-producing regions, particularly the Niger Delta where Pb(II), Cd(II), and Cr(VI) levels exceed World Health Organization guidelines by up to 500-fold. This study addresses this environmental challenge through the development and optimization of...
