摘要
在测定岩石和土壤中的Ag、B、Sn时选用发射光谱法,缓冲剂为碳粉、三氧化二铝、氟化钠、焦硫酸钾等,同时将Ge作为内标元素,不但能改善各元素的蒸发行为,摄谱时间较短,而且降低了光谱背景,对于同时定量测定试样中的Ag、B、Sn,可取得较好测定效果。
Determination of Ag in soils,B,is generally used when Sn spectroscopy,buffers typically carbon,aluminum oxide,sodium fluoride,potassium pyrophosphate,etc.,can improve the evaporation behavior of each element,spectrographic shorterlt reduces the spectral background,while Ge as an internal standard element,simultaneously,quantitative sample of Ag,B,Sn were measured,measured and achieved good results.
