Apr 13, 2021Nanoscale zero-valent iron synthesized from natural and hydrothermal zeolite has a removal rate of 95.1 and 91.3%, respectively, at the pH value of 1.0. The ordinary nanoscale zero-valent iron shows the removal rate of 90% at pH 1.0 and the removal rate decreased incredibly to 10% at pH 6.0 (Tyagi et al. 2018). Nanoscale zero-valent iron has less ability to rapidly oxidize when it is exposed to air during the chemical reaction.
