摘要
用火焰原子吸收法 ,对两种复合肥料及其包膜肥料水溶出液中的养分钾进行了测定 ,测试中的 6个样品平均加样回收率为 1 0 7.89% ,为包膜复合肥料配方设计和释放特性研究提供了准确、灵敏、快速的定钾方法 .
The nutrient potassium of water-soaking solution for two kinds of coatedcompound fertilizer was determined by atomic absorption spectrophotometry,in which the recovery rate was 107.89% for 6 samples and the correct, sensitive and quick potassium is provided for the formula design and release feature research of coated compound fertilizer.
