PENENTUAN Cu DAN Zn PADA BUAH APEL (Malus Sylvestris Mill) DAN BUAH MELON (Cucumis melo L) DENGAN METODA VOLTAMMETRI STRIPPING ADSORPTIF (AdSV)
Abstract: A simple and
reliable method was developed to determinate
Cu and Zn in apple (Malus Sylvestris
Mill) and melon
(Cucumis Melo L)
by Adsorptive Stripping
voltammetry. Studied accumulation potential and accumulation time as the
optimum parameters used in this method.
The results were
obtained optimum conditions
0,3 V accumulation potential and
accumulation time of 120 seconds.
At the optimum
conditions obtained relative standard
deviation of Cu
1,0228% and Zn 4,4298%.
This method was
applied to the determination of
Cu and Zn on apple fruit and melon
fruit. After the measurements of the two samples, found in apple 0,0089 ug/g Cu and 0,0160 ug/g Zn, the melon fruit is 0,0107 ug/g Cu and 0,0087 ug/g Zn. Limit of detection (LOD) of Cu and
Zn is equal to 0,179 ug/g
and 0,1591 ug/g
while quantitation limit
(LOQ) for Cu
and Zn is
0,596 ug/g and 0,5304 ug/g .
