FeCl_3溶液的微波等离子体炬光谱摄谱特点

The Spectrophotographic Character of FeCl_3 Solution with Microwave Plasma Torch

铁谱作为其他元素光谱的标识光谱，在摄谱法元素分析中占有重要地位．为了研究近年新研制出的微波等离子体炬的开发前景，我们用它作为激发光源，对ＦａＣｌ３溶液进行摄谱研究．通过改变等离子体气流量、微波入射功率、焰炬上摄谱高度、曝光时间等条件，获取了具有对比性的谱板．对摄谱结果进行分析，本文总结出对ＦｎＣｌ３溶液较适宜的微波等离子体炬摄谱条件．

The Microwave Plasma Torch(MPT)is a new kind of light source in analysis.The spectrum of Fe occupies an important position.The spectrums of FeCl3 solutio with the MPT are under various conditions,and favourable conditions are presented based on the analysis of the experimental results.
