复混肥中氧化钾含量分析方法技术研究

介绍了火焰光度法测定复混肥中K2O含量的原理、方法,讨论了称样量变化对测定结果的影响,探讨消除影响的方案以确保分析数据准确。该火焰光度法测定准确度及精密度均较高,测定结果与国家标准四苯基合硼酸钾重量法测定值完全吻合,极大地缩短了分析时间,可满足生产中间控制分析对分析数据的要求。

Method for analysis of potassium oxide content in compound fertilizer technology

This article introduced in the flame photometry determination compound the principle and method of K 2 O content, discussed said the effect of type of quantity change on the result, the discussion eliminates the influence the plan to guarantee the analytical data is accurate. This flame photometry determination accuracy and accuracy are high, the results and national standards four benzyl tally about the potassium borate weight method determination value completely, shortened the analysis time enormously, but produces the request of middle controls analysis satisfiedly to the analytical data.
