Identification of Major Organic Constituents in Textile Waste Water Resulting from the Use of Sulfur Dyes.

摘要

The waste water from textile dyeing facilities contains many organic contaminants. A laboratory simulation of the sulfur dyeing of cotton fabrics was done in order to determine the nature of the by-products normally discharged in textile waste water systems. The organic constituents resulting from these laboratory dyeings were removed from water solution using liquid-solid chromatography and XAD-2resin. The organic fractions so obtained in several eluting solvents were further separated by a second separation using silica gel chromatography. These fractions were then examined using various analytical techniques. It was determined that the waste water resulting from sulfur dyeings contained in excess of 200different organic constituents varying in molecular weight and nature of functional groups.
