ANALISIS KANDUNGAN KADMIUM (Cd) DAN SENG (Zn) DALAM KUBIS BUNGA (Brassica oleracea var. botrytis L) DENGAN METODE SPEKTROFOTOMETRI SERAPAN ATOM
Abstract: Flowers cabbage
(Brassica oleracea var. botrytis L) is an important and widely grown vegetable
in many places. Soil as the growth of vegetables such as flowers cabbage can be
contaminated media by harmful substances, such as heavy metals like cadmium
(Cd) and zinc (Zn). Analysis of cadmium and zinc contents in flowers cabbage in
the Koto Baru in Tanah Datar and Padang Lua in Agam by Atomic Absorption
Spectrophotometry has been done. This study aims to determine the content of
cadmium (Cd) and zinc (Zn) in flowers cabbage and to know what kind of a good
solvent on the analysis of the content of cadmium (Cd) and zinc (Zn) in flowers
cabbage by Atomic Absorption Spectrophotometry. This study uses a wet
destruction, where the destruction process done with some variation of the
solvent variation: HClO4 p.a, HNO3 p.a and HNO3-HClO4 mixture (4:1). Research
results showed that local flowers cabbage in Koto Baru Tanah Datar and Padang
Lua Agam is still below the safety limit but still have to watch out for. Good
solvent for analysis of Cd metal content in the sample flowers cabbage for Koto Baru area of Tanah Datar is
HNO3-HClO4 mixture (4:1) for a Padang Lua, Agam is HClO4 p.a good solvent for
analysis of Zn metal content in the sample flowers cabbage for Koto Baru area
of Tanah Datar and Agam, Padang Lua is HNO3-HClO4 mixture.
