| 摘 要： | 由于采用GB/T8574—2002四苯硼酸钾重量法测定复混肥中K2O耗时较长,通过对高锰酸钾容量法测定复混肥料中氧化钾含量的研究和与国标法分析方法结果对比,表明该方法精密度、准确度可满足要求,耗时仅为国标法的1/2。

| Abstract: | The determination of potassium content in compound fertilizers needs to take long time by GB/T 8574-2002 potassium tetraphenylborate gravimetric method, the potassium permanganate volumetric method for determination of potassium content is studied. Compared with the former method, the precision and accuracy of the latter method can meet the requirements, and the analytic time is only half of that. |
