Abstract
ABSTRACT Determination of Cu And Zn in Apple (Malus Sylvestris Mill) and Melon (Cucumis Melo L) by Adsorptive Stripping voltammetry (AdSV) By: Nur Afriyanti (0910412028) Umiati Loekman, M.Si *, Yefrida, M.Si ** * Advisor I **Advisor II Research about determination of Cu, Zn in apple (Malus Sylvestris Mill) and melon (Cucumis Melo L) by Adsorptive Stripping voltammetry method have been conducted. Studied accumulation potential and accumulation time as the optimum parameters used in this method. The results were obtained optimum conditions 0,3V accumulation potential and accumulation time of 120 seconds. At the optimum conditions obtained relative standard deviation of Cu 1,0228% and Zn 4,4298%. Limit of detection (LoD) of Cu and Zn is equal to 0,179 µg/L and 0,1591 µg/L while quantitation limit (LoQ) for Cu and Zn is 0,596 µg/L and 0,5304 µg/L. 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. Keywords: copper, zinc, adsorptive stripping voltammetry.
