Abstract
Sulphuric acid is used in the manufacturing processes of many goods over a wide range of applications. During manufacturing process, it is important to determine concentration of sulfuric acid (H2SO4) accurately at all stages. Currently, titration and refractive index based techniques have been used for detection of H2SO4 acid concentration. Therefore, there is a need of the techniques that can measure concentration of the H2SO4 acid more rapidly with accuracy. In this work, we have demonstrated a Fabry–Perot interferometer based poly (4-vinyl pyridine) coated optical sensor for H2SO4 acid concentration detection at room temperature. The performance parameters of developed sensor in terms of sensitivity, limit of detection (LOD), response time and recovery time for H2SO4 acid measurement at the room temperature were found between the order of 30.7 pm/μL/L, 0.65 μL/L, 120 s and 180 s, respectively.
