实验确定了最佳测定工作条件,利用火焰原子吸收分光光度法测定复(混)合肥料中的氧化钾含量,测定的含量范围较大,可达200mg/L,干扰易消除,操作步骤少、简便,条件易控制,分析速度快,加标回收率达95%-106.8%,RSD为1.3%。经大量试验证明,采用此法测定,方便快速,结果令人满意。
The optimum determination conditions were determined experimentally, and the content of potassium oxide in the compound fertilizer was determined by flame atomic absorption spectrophotometry. The content of potassium oxide in the compound fertilizer was more than 200mg / L, the interference was easy to eliminate and the operation steps were few, Simple, easy to control conditions, fast analysis, spiked recoveries of 95% -106.8%, RSD was 1.3%. After a large number of tests proved that the determination of this method, convenient and fast, the results are satisfactory.
