[Defluoridation of household water].
Fluorine enriched drinking water (1 ppm F-) is partially defluoridated with the aid of a simple (laboratory) apparatus. The material employed is tricalcium phosphate. The pH-values and electrical conductivity due to fluoridation are significantly changed by defluoridation. The duration of the defluoridation process appears acceptable and the efficiency of the system is adequate. The experimental conditions as well as the results show that an acceptable alternative exists to fluoridated drinking water in the household.
