Abstract

This paper reports a method for monitoring of

C in the atmospheric and biological samples. The method involves preparation of carbon dioxide produced from the samples. Acetylene is produced from carbon dioxide sample by lithium carbide formation. A silica-alumina catalyst activated by chromic anhydride employed for the conversion of acetylene to benzene is used. The yield of benzene is about 80% and its purity checked by gas chromatography analysis is better than chromatographic grade benzene. The method is convenient

quick and accurate for monitoring of

C in environmental samples.
