碱土金属元素的微等离子体炬原子发射光谱法测定
DETERMINATION OF ALKALI EARTH METAL BY MICROWAVE PLASMA TORCH ATOMIC EMISSION SPECTROMETRY
【摘要】 用微波等离子体炬原子发射光谱法(MPT-AES)测定了一些碱土金属元素。考察了MPT-AES测定这些元素的条件及共存物的影响情况。测定Be,Mg,Ca,Sr和Ba的检出限分别为0.47,1.4,0.15,0.20和2.6ng/mL。将所确定的方法用于一些实际样品中Ba和Mg的测定,结果准确。
【Abstract】 Determination of alkali earth metal by microwave plasma torch atomic emission spectrometry (MPT AES) was investigated.Operating conditions the effects of some coexistent elements were examined.Detection limits for Be,Mg,Ca,Sr and Ba are 0 47,1 4,0 15,0 20 and 2 6ng/mL,respectively.Method has been applied to analyse some actual samples with satisfactory results.
