【摘要】 分别采用传统王水消解法和微波消解法处理样品,用电感耦合等离子体原子发射光谱法测定土壤中全硫、全磷和全钾的含量。该方法简单快捷,检测灵敏度高,线性范围宽,重复性好,准确度高,能同时测定土壤中全硫、全磷和全钾的含量,测定结果准确可靠,重现性及精密度很好,加标回收率在95.1%~100.4%之间。可使分析工作者从传统的分析手续冗繁、耗时的繁重工作中解放出来。更多还原

【Abstract】 In this paper,the aqua regia digestion and microwave digestion for soil samples were used to determinate soil total sulfur,total phosphorus and total potassium content by inductively coupled plasma atomic emission spectrometry.The method was simple and quick,with high sensitivity,wide linear range,good repeatability,high accuracy,and it could be used for simultaneous determination of total sulfur,total phosphorus and total potassium content.The results were accurate and reliable,with good reproducibility and precision,the recoveries were between 95.1% ~ 100.4%.It could release the analysts from the traditional analysis of redundant procedures and save time.更多还原
