Emoval and recovery of trace Levels of toxic mercury ii and Chromium vi from wastewater using Syzygium jambolanum nut carbon

Abstract

The suitability of the chemically activated carbon prepared by newlinereacting Syzygium jambolanum nut with conc sulphuric acid in the presence newlineof ammonium persulphate followed by thermal activation in CO2 atmosphere newlinefor the removal of toxic inorganics like mercury II and chromium VI has newlinebeen systematically examined by both batch and column experiments The newlinecarbon prepared was designated as chemically activated high temperature newlineSyzygium jambolanum nut carbon CHSJC newlineSystematic studies on the removal of mercury II showed that the newlinecarbon was found suitable for the removal of Hg II in the pH range of newline was removed as anionic complex HgCl4 to prevent the newlinereduction of Hg II to elemental state Hg II was analysed using Direct newlineMercury Analyser DMA newline newline
