Penentuan Batas Deteksi Unsur N, P, K, Si, Al, Fe, Cu, Cd, dengan Aktivasi Neutron Cepat Menggunakan Generator Neutron
ABSTRACT: Determination of
limit detection of the elements N, P, K, Si, Al, Fe, Cu, Cd, with fast neutron
activation using neutron generator has been done. Samples prepared from SRM 2704, N, P, K
elements from MERCK, Cu, Cd, Al from activation foil made in San Carlos,
weighted and packed for certain weight then iradiated during 30 minutes with 14
MeV fast neutron using the neutron generator and then counted with gamma
spectrometry (accuspec). At this
research condition of neutron generator was set at current 1 mA that produced
neutron flux about 5,47.107 n/cm2.s and
experimental result shown that the limit detection for the elements N,
P, K, Si, Al, Fe, Cu, Cd are 2,44 ppm,
1,88 ppm, 2,15 ppm, 1,44 ppm, 1,26 ppm, 1,35 ppm, 1,05 ppm, 2,99 ppm,
respectively. The data indicate that the limit detection or
sensitivity of appliance of neutron generator to analyze the element is very
good, which is feasible to get accreditation AANC laboratory using neutron
generator.
