火焰原子吸收光谱法测定复（混）合肥料中的钾
摘要
The common ways of determining potassium oxide on mixed and compound fertilizer were F1’PB weight, but the ways were too much shortage, such as too much work conditions, too complex operation steps, too uncontrolling reasons, too low determining speed, too large consumings tor medicions, too large working times, too large working strength, too unstable datas. The detection founded the west determining conditions for determining potassium oxide on mixed and compound fertilizer with flame atomic absorptiom. Spectrometry, it had large ranges for determining which were 200 mg/L, small disturb, little operation steps, ersy controlling reasons, quick determining speeds, little machines and glasses we used, little consumings for medicions, less shorter working times, less working strength, high recoveries for adding Standard matter which were 95%-106.8%, low RSD (RSD (n=11) were 1.3%), much stable datas. Through many tests we know: the detection was a convenient, quick, agreeding method we used.
