The research explained the effect of coating polymethyl methacrylate (PMMA) and polyvinyl alcohol (PVA) of tapered microfiber as sodium hypochlorite liquid sensors. The taper microfiber was designated using a technique known as "flame brushing" from SMF-28 silica fiber. The parameter for the size of taper microfiber is named as a middle diameter Dm and length diameter Dl. The taper microfiber was then coated with PMMA and PVA, respectively. The sodium hypochlorite concentration ranges from 1 ppm to 6 ppm. The liquid was then used with coating and non-coating taper microfiber as sodium hypochlorite sensors for analysis purposes. The coating and non-coating taper microfiber's performance as a sensor is defined by sensitivity, linearity stability, and repeatability results. The results show that the taper microfiber's sensitivity and linearity achieve >1.0 dB/ ppm and linearity >90, respectively. The stability and repeatability showed promising performance of all taper microfiber conditions. © 2024 Wydawnictwo SIGMA-NOT. All rights reserved.
