This standard specifies the visual determination of fluoride in drinking water, surface water, groundwater and wastewater using zirconium alizisulfonate Colorimetry. The minimum detection concentration of this method is 0.05mg/L, and the upper limit of detection is 2.5mg/L. Pre-distillation is required when the interfering ions in the sample exceed a certain concentration. The determination is based on the color change of the fluoride ion and zirconium alizisulfonate complex, and the fluoride content is determined by visual Colorimetry.
