Analysis Content Of Cupri (Cd) And Manganese (Cu) In Carrot (Daucus Carota L.) With Atomic Absorption Spectrophotometry Methods
Abstract: Carrots (Daucus
Carrota L.) is widely grown vegetables. Soil as the growth of vegetables such
as carrots can be contaminated media by harmful substances, such as heavy
metals. Has done research on the analysis of copper and manganese in the
carrots in the area Talago Koto Baru, Tanah Datar and area Bangkaweh,Agam with
Atomic Absorption Spectrophotometry method. This study aims to determine the
content of copper (Cu) and manganese (Mn) in the carrots and to determine the
type of good solvent in the analysis of copper (Cu) and manganese (Mn) in
carrot by Atomic Absorption Spectrophotometry method. This study uses a wet
destruction method, where the destruction is done with some variation of the
solvent variation: pa HClO4, HNO3 pa, pa and HNO3-HClO4 (4:1). Research results
showed that carrot in the area Talago Koto Baru, Tanah Datar and area
Bangkaweh,Agam is still below safe limits but should still be on the alert.
Best solvent for metal content analysis of Cu and Mn in the sample carrots for
area Talago Koto Baru, Tanah Datar and area Bangkaweh, Agam is HNO3 pa.
