Determination of the Trace Elements in Psidium guajava L.Fruits by Atomic Absorption Spectrometry
”Objective” The aim was to establish a method for determining the trace elements in Psidium guajava L.fruits.”Method” Cu and Zn were determined by FAAS and Ni,Cr,Pb,As,Cd and Hg by GFAAS.”Result” Among these samples,content of Cu was the highest,while contents of Zn,Cr,As,Ni,Pb,Cd and Hg were lower.The sample recovery rates of Cu and Zn were found in the range of 99.2% -100.4%,and those for Pb,Cd,Cr,Ni,As and Hg were among the range of 97.6% -102.1%,with all the values of RSD less than 4.46%.”Conclusion” This method was simple,rapid,sensitive and accurate.It could be used for determining the content of trace elements in Psidium guajava L.fruits.
