Spectrophotometric Determination of Carbon Disulphide in the Workplace Air

Abstract EN

This papre describes a simple method of carbon disulphide determination in the air of working environment in the chemical companies and plants after its absorption into aprotic N,N-dimethylformamide solvent.

Carbon disulphide absorbed into aprotic solvent was transformed by using ammonium hydroxide on sulphides which were determined by spectrophotometry.

5,5′-Dithiobis(2-nitrobenzoic acid) and blue tetrazolium chloride were used as chromogenic sensing reagents.

Colour-reducing products were measured at the wavelength of 500, respectively 520 nm.

Detection limits for determination of carbon disulphide in the air are 0.2, respectively 0.4 mg·m−3.
