Influence of pre-oxidation with potassium permanganate on the efficiency of iron and manganese removal from surface water by coagulation-flocculation using aluminium sulphate: Case of the Okpara dam in the Republic of Benin

    Okpara dam water contained significant amounts of iron and manganese that could   create problems for consumers. This study perfected a deferrization and demanganization technique preceded or followed by oxidation with potassium permanganate. The maximum iron and manganese contents varied from 30 to 50 and 1.5 to 4.5 mg/L respectively. Under the best conditions, simple...

A slurry sampling hydride generation atomic absorption spectrometric method for speciation analysis of trace inorganic arsenic in flours

  A novel hydride generation atomic absorption spectrometric method is developed for speciation analysis of inorganic arsenic in flours. This method is based on the leaching of arsenic from sample slurry through the sonication followed by hydride generation in the slurry and determination of the corresponding hydrides. The content of arsenic (III) [As(III)] was determined under 1% HCl acidity condition using...
