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
