Analisis Pengaruh Kandungan Logam Berat Terhadap Energi Pembakaran Batubara
Abstract: The research has
been conducted to determine the effect of heavy metals on coal, where the coal
comes from three different places in Indonesia. The collection and testing of
samples was conducted by PT Sucofindo Padang branch. From the sample tested,
the combustion energy is 6562 Kkal / Kg, 6331 Kkal / Kg and 6375 Kkal / Kg, for
coal with initials A, B and C. Heavy metal testing is done using Atomic
Absorption Spectrophotometer (SSA). From the test, the biggest metal
concentration is metal potassium (K) followed by other metal. From the data it
can be seen that Iron (Fe), Mangan (Mn), Lead (Pb) and Potassium (K) if the
concentration is large, the combustion energy is small. While the two metals of
Magnesium (Mg) and Calcium (K) have no effect at all. In Aluminum (Al) and
Copper (Cu) metals if the concentration is large the energy is also large.
