消解炉消解-氧化还原滴定法测定土壤样品中有机质

Determination of Organic Matters in Soil Samples by Oxidation-Reduction Titration with Furnace Digestion

    摘要
  • 摘要: 沿用经典重铬酸钾氧化-外加热法的原理，建立了消解炉消解-氧化还原滴定法测定土壤样品中有机质的方法。实验选择消解温度为180—200℃，消解时间为10—15min。方法用于大批量区域多目标地球化学调查样品中有机质的分析，测试值与标准值相符。对国家土壤标准物质进行测定，方法精密度（RSD，n=8）为1．93％～7．96％。

     

    Abstract: Based on the principle of classical potassium dichromate oxidation-outer heating, a method for the determination of organic matters in soil samples by oxidation-reduction titration with furnace digestion was proposed. The digestion condition was optimized
