| Abstract: | A new analytical method of ion selective electrode,that is,equal potential difference-ion selective electrode,has been developed. This method has been applied to determine fluoride.Inspection with standard sample containing fluoride has been done.The determination results for standard sample were consistent with theoretic value.The analytical results for sample were in keeping with those obtained by spectrophotometry.The ashing conditions for samples were studied. |
