| Abstract: | Uncertainty of using ion selection electrode to measure concentration of fluoride in water and wastewater was assessed. The uncertainty caused by different heft composing standards such as levels of fluoride and different sample volume was also investigated. Levels of fluoride include three uncertain hefts namely standard curve, precision of instrument and standard solution preparation. Expanded uncertainty was obtained if assuming coverage factor of 2. |
