The AAS Method for Arsen Analysis in Cabbage in the Area of Sinabung Post Eruption

Abstract

Sinabung erupts will emit hot clouds. Flowing lava will bring considerable heat. Negative Impact after the eruption of this mount is the exposure of cauliflower plants around the eruption site by Arsenic. This study aims to determine of Arsenic from various types of cabbage (white, purple, green) exposed to the Sinabung area after eruption using the Atomic Absorption Spectrophotometry (AAS) method. The sample used is stem from white, purple, and green cabbage. Preparation of green cabbage samples in analytical laboratory Universitas Sumatera Utara. Sampling uses simple random sampling technique. Process of destruction have been developed and analysis using the Atomic Absorption Spectrophotometry (AAS) method used standard solution at 0.05, 0.10. 0.150. 0.20. and 0.250 μg / mL. The wavelength used is 193.7 nm. The results of the analysis showed that the amount of Arsenic contained in white, purple and green cabbage stems was 0.0072, 0.0043, and 0.0082 μg / mL respectively.
