有机化合物在900℃高温,于氮气流下瞬间裂解生成的各种氧化物,经900～950℃的铂碳层还原成一氧化碳。一氧化碳再经过350℃氧化铜层氧化成二氧化碳,最后用20mA恒电流对二氧化碳进行库仑滴定,由光度检测作终点指示。每次分析时间为15分钟,标准偏差为0.5％。本法已应用于常规分析。对含磷、铁、铜等金属有机化合物,在样品上复盖一些铂碳也可获得满意的分析结果。
Organic compounds at 900 ℃ high temperature, under a stream of nitrogen instantaneous cracking of the resulting oxide, platinum and carbon layer by 900 ~ 950 ℃ reduced to carbon monoxide. Carbon monoxide is oxidized to carbon dioxide by a copper oxide layer at 350 ° C, and finally the carbon dioxide is coulometric titrated with a constant current of 20 mA, and the end point is indicated by photometry. Each analysis time was 15 minutes with a standard deviation of 0.5%. This Law has been applied to routine analysis. For phosphorus, iron, copper and other metal organic compounds, the sample covered with some platinum carbon can also be satisfied with the results of the analysis.
