摘要
简单介绍了GB/T8572-2010复混肥料中总氮含量的测定蒸馏后滴定法中一点可以讨论之处--用硫酸标准溶液代替原来的硫酸粗溶液,新方法不再需要进行空白试验。两种方法相比结果符合方差要求,新方法在最大限度上节约了人力、物力,可以在实际工作中应用。
This article introduces fertilizer titration after distillation acid instead of the method. Compared original crude to the results the GB/T8572 -2010 determination of total nitrogen content compound can be discussed in a little place - with a standard solution of sulfuric solution of sulfuric acid and the blank space test isnt needed in the new with the original method, the two methods can both meet the variance requirements. The new method can save the manpower, material resources in most degree and can be usedin practice.
