Evaluation of a Reductiometric Titration Method for Determining Quinones in Soil Humus1
- S. P. Mathur2
A SnCl2-I2 reductometric titration method gave values of 4.2 and 3.5 meq quinoid carbonyls/g in a soil fulvic (FA) and humic acid, respectively. The results were supported by the analysis of a mixture of the FA and a napthaquinone, and were in agreement with earlier enzymatic and infrared studies of the soil humic compound. No reduction of the nonquinoid carbonyl of benzophenone by SnCl2 was observed.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
