Fluoride determination in urine with ion selective electrode: Within laboratory method and sample storage optimization
Original language description
This work presents method validation of fluoride determination in urine of children. The fluoride ion selective electrode and silver chloride reference electrode have been used for all measurements. We have found that described method is accurate (average recovery 98.4 %) and provided precision RSD = 2.8 %. The evaluated value of limit of detection using direct signal method has been 3.2.10-6 mol.l-1. The fluoride concentration in real urine samples is influenced during the storage in the refrigerator (+ 4 °C). The samples should be stored deeply frozen at - 20 °C before the analysis. The comparison of several buffers (commercially available TISAB, citrate buffer with different pH and citrate buffer with NaCl) leads to the conclusion that there is no significant difference among used buffer solutions.
