Abstract

1421957 Purifying water INSTITUT TEXTILE DE FRANCE 11 June 1973 [9 June 1972] 27649/73 Addition to 1286535 Heading C1C [Also in Division C3] Cellulose substituted by quaternary ammonium groups of the general formula wherein R, R<SP>1</SP> and R<SP>11</SP> are alkyl radicals (preferably methyl) having from 1 to 3 carbon atoms each X- is an anion and n a positive integer, may be used in powder form as an anion exchange material to remove contaminants from industrial waste water. In Example 1 sulphur black rinsing water is forced through a filter with a preliminary layer of substituted cellulose. In Example 2 a column of the cellulose is used to decolorize hydrone blue rinsing water. In Examples 3 and 4 water from a galvanoplastics plant is treated by passing through a filter of the cellulose to remove CN- and Cr 2 O 7 - ions respectively.
