Determination of Trace Elements in Mulberry Silkworm by Flame Atomic Absorption Method

[Objective] To determine new resources of mulberry silkworm and determine the contents of ten elements in silkworm chrysalis.[Method] The contents of K,Na,Ca,Zn,Fe,Cu,Mg and Mn in silkworm chrysalis were determined with flame atomic absorption spectrophotometry,and the contents of Se and Cr were determined with graphite furnace atomic absorption spectrophotometry.[Result] The contents of K,Na,Cu,Zn,Fe,Ca,Mg,Se,Cr and Mn were 14.340 0 mg/g,49.380 0 mg/g,22.580 0 μg/g,142.400 0 μg/g,450.600 0 μg/g,8.567 0 mg/g,4.783 0 mg/g,0.458 1 μg/g,1.815 0 μg/g,and 18.580 0 μg/g.[Conclusion] The established flame atomic absorption method is simple,rapid,sensitive and accurate,and silkworm chrysalis is very nutritional,thus it has broad application prospect.
