Abstract
A novel method has been developed for the separate determination of in organic and organic forms of carbon in soil, which has been used in an analyzer that employs a photoacoustic method of recording the CO2 rel eased. The soil is combusted under reduced pressure with a saturated s olution of potassium dichromate in concentrated sulfuric acid, which g ives results more correct than those from Tyurin's method because of t he increased oxidation of the organic material. The method also enable s one to determine the carbon in soil carbonates on the same specimen. The total time for the separate determination is not more than 15 min .
