Abstract
A direct colorimetric method is described for determining sodium isethionate (2-hydroxyethane sulphonate) in aqueous solution by means of its red complex with ammonium ceric nitrate. Ethylene glycol, if present, is removed from the sample by extraction with ethyl acetate before colorimetric determination.The over-all precision of the method is within ±1 per cent.Keywords
