A modified field test for the determination of carbon disulphide vapour in air

Abstract

An improved and more sensitive method is described for the determination of carbon disulphide vapour in air at concentrations up to 40 p.p.m. V/V. Carbon disulphide vapour is absorbed from a 500-ml sample of air into an ethanolic solution containing copper(II) acetate, diethylamine and triethanolamine. The yellow colour produced is compared visually with standard colours or measured spectrophotometrically. For field use, the apparatus is portable and simple to operate, and requires a working time of about 5 minutes per determination.
