摘要: 本文从理论和实验两方面进行了温度对流动注射分析中溶液分散影响的研究。结果表明,随着溫度升高,峰高值增大,半峰宽减小,保留值延长,峰面积则基本不变。增大进样体积和流速能够减小温度对峰高、半峰宽和保留时间的影响程度。

Abstract: In this paper the influence of temperature on the diffusion of solution in flow-injection analysis is studied.The theoretical and experimental resuts show that the peak height and residence time increase and the half width decreases, with increasing temperature,whereas the peak area keeps constant. With increasing of the sample volume and flow rate,the influence of temperature on peak height residence time and half width can be decreased. These results are theoretically explained.

Key words: Temperature, Flow-injection analysis, Diffusion of solution
