Nanoscale zero-valent iron – Characterization and analytical application [PDF]
, 2017 Nanomaterials have gained the greatest interest over other materials as the adsorbents of analytes such as transition metals and semimetals from complex environmental samples. [1] Utilization of zero-valent iron nanoparticles (nZVI) is widely adopted in analytical preconcentration and extraction procedures due to large surface area, chemical stability,
