采用水平炬管设计的Optima3000DV全谱直读等离子体发射光谱仪 ,利用端视与侧视观测方式相结合 ,多元光谱拟合 (MSF)校正光谱干扰 ,用纯标准溶液配制混合标准系列作校准曲线 ,同时测定了土壤、沉积物和植物中Al、Ca、K、Mg、Na、Fe、Ti、As、Cd、Co、Cu、Mn、Mo、Ni、P、Pb、V、Zn18个常量、微量元素。经几个国家标准样品的验证 ,测定结果与推荐值基本相符 ,实际样品回收率土壤在92%～105 %之间 ,蔬菜在87.8%～104%范围。相对标准偏差分别为0.28%～4.23 %和0.26 %～3.66%。
Using the horizontal torch design Optima3000DV full-spectrum direct-reading plasma emission spectrometer, the use of end-of-line and side-by-side observation of the combination of multiple spectral fitting (MSF) to correct spectral interference, mixed with a standard solution prepared by mixing standard series of calibration curves, At the same time, 18 constants of Al, Ca, K, Mg, Na, Fe, Ti, As, Cd, Co, Cu, Mn, Mo, Ni, P, Pb, V and Zn in soils, sediments and plants were determined. Trace elements . After verification of several national standard samples, the measured results are basically consistent with the recommended values. The actual sample recovery rate is between 92% and 105% of the soil and 87.8% to 104% of the vegetables. The relative standard deviations were 0.28% -4.23% and 0.26% -3.66% respectively.
