Ca. Zn. Cu. MnandFe in GarlicbyMicrowaveDigestion- AtomicAbsorption Spectrometry LI Zhong- liang, HUANG Zhi- wei ( Dep ar tment of Chemistry and B iology , Yulin Teachers Colleg e, Yulin Guangxi 537000, China) Abstract: Content of MgC ZnCuMn nd Fe in g rlic h s been determined by microw ve digestion- tomic bsorption spectrometry (AAS) . Results indic te, th t microw ve digestion technique is f st , simple method of s mple tre tment, the technique lso c n s ve re gent nd void polluting environment . In this experiment , the r te of recovery is 996% ~ 1003% , w ith rel tive st nd rd devi - tion 0 725% , which suggests th t the method of AAS is convenient nd ccur te to determine these elements . Results lso suggest th t useful met l elements re bund nce in g rlic .
