Abstract

This article discusses a chemo- mechanical- optical sensing approach for detection of toxic Chromium metal ion in environment. Stimulus responsive hydrogel which swell/deswell depending on ambient chromium ion concentrations, is agglutinated on Fiber bragg grating (FBG) surface. The sensor shows good sensitivity for Chromium. Cr ion concentration down to 10ppb can be sensed by the method.
