%T ANALYSIS OF WASTE SAND AT DIAMONDS MINING
CEMPAKA BANJARBARU
%K cempaka sand, atomic absorption spectroscopy (AAS)
%X We had analyzed the content of waste in sand on around the diamond mining in Cempaka Banjarbaru
South Kalimantan. The method that was used with atomic absorption spectroscopy (AAS). AAS is a
spectroanalytical procedure for the quantitative determination of chemical elements using the absorption
of optical radiation by free atoms in the gaseous state. The result showed that metal in the sand as
material research is silica (Si) of (41.4345 ± 0.5581)% and Iron (Fe) of (2.7769 ± 0.0371)%. This results
information of Cempaka’s sand analysis are expected to be used as basis for optimal utilization of sand.
