This standard specifies the standard analytical method for the determination of aluminum, calcium, magnesium and iron in boric acid by inductively coupled plasma optical emission spectrometry. This standard is applicable to the analysis of aluminum, calcium, magnesium and iron in boric acid. When the sampling amount is 1g boric acid, the determination range of aluminum is 0.20 μg/g~50 μg/g, and the determination range of calcium is 0.25 μg/g~100 μg. /g, the measuring range of magnesium is 0.18 μg/g~100μg/g, and the measuring range of iron is 0.27μg/g~20μg/g.
