A method of determination of fluoride content in calcined magnesite by microwave dissolving-ISE was set up.The interference elimination on logarithm calibration curve was studied.The results showed as follows: the samples were dissolved completely,the matrix interference,was eliminated.The recovery was 85%-96%.This method is able to rapidly determine the low content of fluoride in calcined magnesite.
