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.

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.
