Open publisher page 0 citations

Abstract

FAAS/secondary sensitivity detection line method on determining the magnesium oxide content in the phosphate was researched.The recovery was 98.1～102.3%,standard deviation was less than 0.03,coefficient of variation was less than 1.9%,the range of linearity was 2～50 μg/ml.The method was easy to use and took little time,and has a large scope of application.
