Uji Perbandingan Metoda AANC dan AAS untuk Analisis Cu, Cd, Cr, and Pb pada Sedimen Sungai Code (Indonesia)
ABSTRACT: Comparison test of
Fast Neutron Activation Analysis (FNAA) and Atomic Absorption Spectrometry
(AAS) method for analysis of Cu, Cd, Cr, Pb elements in Code river sediment
samples has been done. Comparisons of test used Standard Reference materials
(SRM) sample, covering the validation test, t test and F test for both method
and then these methods were used to analyze the Code river sediment samples.
Comparisons test result show that the validity of both method are around 92.69
% to 98.12 % and t test show that there is no significant difference in average
concentration, F test of both methods show that there is no difference in
accuracy. The analysis result of Code
sediment using FNAA for Cu, Cd, Cr, Pb are (15.41 - 53.92) ppm, (1.82 - 3.66)
ppm, (14.72 - 87.28) ppm, (18.23 - 109.31) ppm respectively, while those using
AAS method are (13.71 - 51.11) ppm, (1.64 - 3.33) ppm, (12.81 - 86.75) ppm,
(15.74 - 105.53) ppm, respectively. Statistic result test using ANOVA method
showed that the concentration of Cr are not significantly differences within sampling
locations, while those for Cd, Cr, Pb show a significant difference within
sampling location
