【 摘 要 】

Sulfide gas monitoring is required to protect organisms from its toxicity. Nanoparticles of metal oxides have characteristics that applicable as sensors for controlling environmental pollution like sulfide gas. Thin film of SnO2as one part of the sulfide gas sensor was synthesized with the chemical liquid deposition method, and characterized by UV/VIS/NIR-Spectrophotometer before and after gas application, also using FTIR, SEM and XRD. Characterization studies showed nanoparticle sizes from the diameters range of 38-71 nm. Application of SnO2thin film to sulfide gas detected by UV/VIS/NIR Spectrophotometer with diffuse reflectance showed chemical reaction by the shifting of maximum % R peak at wavelength of 1428 cm. The benefit of measurement of sulfide gas using this SnO2nano thin film is that it could be done at the room temperature.
