Analisa Unsur Fe Pada Tanah ditaman Agronovasi Balai Pengkajian Teknologi Pertanian( Bptp) Sumatera Utara (Sumut) Mengunakkan Alat Spektrofotometer Serapan Atom (Ssa)

Abstract

Analysis is an activity carried out in the laboratory to check the content of a substance in the sample. Where the analysis used aims to determine the Fe (iron) content in the 5 soil samples that have been provided. In determining the Fe content, the SSA method is used. quantitative elemental analysis whose measurements are based on the absorption of light with a certain wavelength by metal atoms in a free state. From the analysis that has been done, it can be seen that Sample A contains high Fe elements (408 ppm), Sample B contains high Fe elements (373 ppm), Sample C contains sufficient Fe elements (132 ppm), Sample D contains high Fe elements. high (271 ppm), Sample E contains sufficient Fe (170 ppm).
