Abstract

This research investigated evanescence field effect using a microfiber as a sodium hypochlorite sensor. The microfiber was built using the "tapering" approach, which transformed silica fiber SMF-28 into a micro size with the diameter is 10micro. The microfiber is then employed as a sodium hypochlorite sensor with a range of sodium hypochlorite concentrations ranging from 50% pmm to 100% pmm. The microfiber performance is clearly excellent, as measured by sensitivity based on wavelength shift. The linearity defined more than 99% is defined as a performed sensor. This microfiber repeatability makes them promising as sodium hypochlorite sensors.
