Fluoride determination can be performed photometrically with alizarin red and Zirconium acid solution, obtaining the following data in the calibration: (View Table) 100.0 mL of well water are measured and concentrated to 50 ml by evaporation, the alizarin and zirconium reagents are added (in quantity proportional to the standards) and after the appropriate time, the reading of the instrument (under the same conditions instrumental) reports an absorbance of 0.182. How much fluoride in mg / L does the well water sample contain?
