【摘要】 <正> 海洋沉积物中有机质的测定,主要有三种方法:（1）湿氧化法:a.加入过量氧化剂,然后进行回滴（例如重铬酸钾-硫酸法）,b.产生CO₂直接测定;（2）高温燃烧法;（3）样更多还原

【Abstract】 The suitable conditions to determine the organic materials in marine sediments by wet oxidation have been found. The soil is ignited at 1000℃ as blank control. The digestion temperature for samples is controlled at 170±2℃ for 10-15 min. This techtique has been applied to determining samples of marine sediments with excelleat precision of lesss than 0.02%.更多还原
