Systematic Analysis of Organic Industrial Wastes

Abstract

and quantitative characterization of the organic constituents of industrial wastes is important in the solution of problems of stream pollution abatement. Specifically, complete or even partial resolution of organic wastes would aid in: determination of actual loads of pollution, studies of methods of treatment, isolation and identification of materials toxic to animal life, studies of persistence of identified waste components in waters, studies of recoverable waste components, studies of causes of tastes and odors in drinking water, and studies of the applicability of the oxygen consumed and biochemical oxygen demand tests to wastes and waste components.

Volatile components of hardwood sawdust smoke. Components of phenolic fraction

“…Isolation of Phenol Fraction from Smoke Condensates. A phenolic fraction was prepared from the aqueous smoke condensate by fractionation based on acidity (Braus and Middleton, 1952). The condensate was diluted to a volume of 100 cc.…”

Combined gas chromatography-mass spectrometry in flavor research. Methods and applications

“…Major effort was directed toward identification of the less volatile phenolic components of wood smoke condensates, since these compounds have been implicated as significant contributors to smoke flavor (Fiddler et a[., 1966;Wasserman, 1966). A phenolic fraction was prepared from an aqueous smoke condensate by fractionation based on acidity (Braus et a[., 1952). A chromatogram of a 20-11. sample of the phenolic fraction was obtained on a packed SE-30 preparative column ( Figure 5).…”

Review - Water Analysis

“…Middleton, Braus, and Ruehhoft (152) reviewed the activated carbon filter technique for sample collection in streams, and described the use of infrared for analysis of the extract from the columns. Braus, Middleton, and Ruehhoft (24) reported on developments in their scheme of analysis of organic matter by solubility differences. The compounds are broken down into four categories: phenolic compounds, acidic compounds, amphoteric compounds, and water-soluble nonvolatiles.…”
