Synthesis and characterization of iron-manganese oxide adsorbents from actual drinking water treatment residuals for hexavalent chromium removal

Waste streams are discharged from electroplating units and similar industrial operations containing high concentrations of toxic hexavalent chromium *Cr VI) ions. In this study, novel adsorbents for Cr (VI) removal were synthesized by coating sand with drinking water treatment (DWT) residuals. The e...
