摘要
本文介绍了脱水改性黑液中（总）水溶性有机物含碳比的测定方法．该法适于我系新产品．也适于其它类似产品的含碳比的测定．测得脱水改性黑液的含碳比为0．451，允许差范围±0．011，结果的变异系数1．6％，表明该法具有较高的准确度和精密度．
The determination method for carbon-content ratio of total organics in dehydrated and property-modified black liquor was introduced. This method was suitable for analyzing the C-Content ratio in our new products and similar products. The C-content ratio of dehydrated and propertymodified black liquor is 0. 451,the permissable error range is ±0. 011 and the coefficient of variation is approximately1.6%. So the accuracy and precision of this method are fairly higher.
