Description:This standard stimulates the determination of organic carbon in soil potassium dichromate oxidation - spectrophotometric method.
This standard applies to dry on the determination of organic carbon in soil. This standard does not apply to the chloride ion content is greater than 2.0 * 10 < > superscript 4 mg/kg of the determination of soil salinization or alkalization of the soil.
When the sample weight is 0.5 g, the detection limit of this regulation is 0.06% (by dry weight), the determination of lower limit of 0.24% (dry weight).
