AbstractCommonlydetermining alkali metals element in cement adopts the flame luminosity
(FL)methodThe experiment scheme and the method of eliminating disturbing elements are re searchedstate standard samples are used in contrast testThe error is less than that provided in
national standardThe method can meet routine test requirements
Key wordsflame luminosity methodpotassium sodium cement
