Analisis Kandungan Mangan (Mn) dan Tembaga (Cu) dalam Bijih Mangan di Daerah Taming Tonga Kecamatan Ranah Batahan Kabupaten Pasaman Barat Secara Spektrofotometri Serapan Atom
Abstract: A research on the
analysis of Manganese and copper content in the manganese ore in the area
Taming Tonga artifacts using atomic absorption spectrophotometry had been done.
This study aims to determine the content of manganese (Mn) and copper (Cu) with
variation of solvent, particle size variations, and solvent volume variations
in atomic absorption spectrophotometry. This study uses a wet method of
destruction, the destruction process is done with some variation of the solvent
variation: concentrated HCl, concentrated HNO3 and HCl-HNO3 concentrated
(3:1), variations in particle size is ≤ 63 μm,> 63 - ≤ 75 μm, and> 75 - ≤
90 μm and variations in volume 20 mL, 25 mL, 30 mL, 35 mL, 40 mL. The results
of this study showed the highest manganese content in the samples obtained by
using Aquaregia 30 mL that is 57 % with particle size ≤ 63 μm while the highest
levels of copper in samples obtained by using a solvent which is 1,89 % HCl 25
mL with particle size ≤ 63 μm best.
