摘要
根据GB-T 8574-2010《复混肥料中钾含量的测定四苯硼酸钾重量法》,对复混肥料中钾含量测定进行不确定度评价,并建立数学模型,对测定过程中的各影响因素进行分析。结果表明,复混肥料中钾含量的扩展不确定度为0.06%,含量测定结果为(13.68±0.06)%。
According to GB/T 8574-2010 Determination of potassium content for compound fertilizers-Potassium tetraphenylborate gravimetric method, the uncertainty in determination of potassium content in compound fertilizer was evaluated, the mathematical model was established, every influence factors in the determination were analyzed.The results showed that the expanded uncertainty was 0.06%,and potassium content was（13.68±0.06）%.
