Abstract

A method for in-situ monitoring the solution volatilization without successive solution extraction based on tilted fiber Bragg grating (TFBG) is presented and experimentally demonstrated. By measuring and analyzing the uniquely enriched spectral characteristics of TFBG, the alcohol volatilization behavior in the binary solution of alcohol-glycerol has been illustrated. The evolution of alcohol volatilization shows a negative exponential trend. During the volatile time of 0 ~ 50 h, the alcohol concentration is reduced from 50% to 15.93%. Using this method, we can conveniently construct a real-time, remote, and in situ monitoring system for gas- and liquid-phase mass transfer, and it is capable of being employed in harsh environment because of its all-fiber structure.
