A Rapid Semi-Micro Method (SMM) for QuantitativeDetermination of Organic Carbon in Soil

摘要

A rapid semi-micro digestion technique for the determination of organiccarbon was described. Our approach was stressed on the dichromate digestionprocess of organic carbon in soil. We optimized digestion temperature and time,adapted potentiometric titration for organic C detection. Optimal digestion conditionwas heating at 140oC(block set temperature) and holding for 30min. The method wascompared with classical wet method and a good agreement was achieved.
