Respike experiments showed that the enhancement from magnetization carries over from magnetization to sulfidation, but not the reverse. Applications of zerovalent iron (ZVI) for water treatment under aerobic conditions include sequestration of metals (e.g., in ,acid mine, drainage) and decolorization of dyes (in wastewaters from textile manufacturing).
