Abstract

Water for dilution of the dialysis solution must be pratically free of contaminants to guarantee the health security of dialysed patients. The treatment of the potable water for this use must be able to eliminate the majority of the fluoride ions. The use of water with high concentrations of these íons is related to the development of osteopathias such as osteoporosis and osteomalacia, The ion-selective electrode method is considered the best one for measuring the fluoride ion in potable waters, because it has high selectivity, good linearity and poor sensitivity to interferences, when compared to the spectrophotometric method. hiperkalemia, among others. The ion-selective electrode method is considered
the best one for measuring the fluoride ion in potable waters, because it has high selectivity, good linearity and poor sensitivity to interferences, when compared to the spectrophotometric method. The main objective of this research was to test the application of this method to measure low concentrations of fluoride ions in waters used to dilute dialysis solutions. Six different compositions of buffer solutions were investigated, with and without the addition of standard solution, ranging from 0 to 2.5 mg/L of fluoride ion concentration. The best results were obtained using buffer solution prepared with...
