To guarantee the accuracy of determining fluorinion in environmental monitoring,ion selective electrode was used.The influence factors were analysised and research results were showed that pH 5~6,Consistent temperature,mixing moderate,response time is 3~5 min,the fluorine electrode was washed clearly so that blank potential is near to that of standard curve.Accuracy of measurement results was higher.
