목적：건립삼규산미중미적함량측정방법。방법：양품미파소해처리후，화염원자흡수광보법측정양품중미적함량。결과：미재0．05-0．4mg／L범위내선성관계량호，상관계수위0．9995；회수솔재98．4％-102．9％，RSD위1．5％。결론：해방법간단、쾌속、준학；능흔호지용우삼규산미중미적질량공제。
To establish a method to determine magnesium in magnesium trisilicate. Method： The sample was handled by Microwave Digestion System, the content of magnesium in the samples was determinated by FAAS. Result： The good linear relation was determined as 0.05-0.4 mg.L-1 in magnesium by FAAS with a regression coeffcient of 0.9995. The average recovery rate was 98.4%-102.9% ;The relative standard deviation was 1.5%. Conclusion：The method was simple, rapid and accurate, and can be used for quality control of magnesium in magnesium trisilicate.
