Abstract

Mercury (Hg) is one of the toxic metal which will danger the human body. To detect this metal in the samples, many instrumentations have been employed such as Atomic Absorption Spectrophotometry (AAS). In this research, Hg was analyzed using Solid Sampling Atomic Absorption Spectrophotometry (SS AAS) where its sample is in the solid form.  The preparation of sample was done using Freeze Dryer, an instrument that allows the sample to dry in the low temperature. The experimental result showed that the method has accuracy of 98,65%, precision of 98,34% and limit of detection of 0,00029 ng/g. Hg concentration in the sample was also found to be sebesar 335,069 ng/g with its relative uncertainty and wide uncertainty is 3,7274 ng/g and 7,4548 ng/g respectively.
