Adsorption of vanadium with amorphous hydrated chromium oxide

Vanadium is recognized as a potentially dangerous pollutant following closely behind lead, mercury and arsenic. Vanadium removal from wastewater prior to discharge is essential. In this work, an amorphous hydrated chromium oxide was prepared and its vanadium adsorption ability studied. As prepared,...

description Vanadium is recognized as a potentially dangerous pollutant following closely behind lead, mercury and arsenic. Vanadium removal from wastewater prior to discharge is essential.
