Ion exchange resins an functional fibres: a comparative study for the treatment of brine waste water
(University of the Western Cape, 2009)
To improve the adsorption capacity of polyacrylonitrile (PAN) fibres, hydrophilic amidoxime fibres were prepared by subsequent conversion of the cyano groups to an amidoxime group by reacting with hydroxylamine at 80°C at ...
Active neutralisation and amelioration of acid mine drainage with fly ash
(University of the Western Cape, 2009)
Fly ash and AMD samples were characterised by standard analytical methods for selection of the test materials. Active treatment by means of mixing fly ash with AMD in beakers and a large tank at pre-determined ratios have ...
Active neutralisation and amelioration of acid mine drainage with fly ash
(University of the Western Cape, 2009)
Due to the constraints being placed on water resources and a drive for major industries to recycle waste water, improved and cheaper water treatment technologies are being investigated. During mining, pyrite (FeS2), a ...
