PHOSPHOR AND NITROGEN ELEMENTS ANALYSIS IN TAPIOCA WASTE PRODUCTS BY NEUTRON BEAM ACTIVATION

PHOSPHOR AND NITROGEN ELEMENTS ANALYSIS IN TAPIOCA WASTE PRODUCTS BY NEUTRON
BEAM ACTIVATION. The analysis of phospor and nitrogen elements in tapioca wasteproducts by neutron'
beam activation analysis have been done. The 14,3 MeV fast neutron beam was produced by Neutron
Generator (Sames trade-mark, type J.25-150 KeV) from JH(d.nlHe nuclear reaction.The side products of
tapioca industry was tapioca waste with P and N contents. The tppioca waste was usedfor raw material of
fertilizer. The quantitative analysis by the relative method was usedfor the determination of the percentage
of phosphor element concentration. It wasfound that the total phosphor element concentration in the upper,
middle and lower layers of tapioca waste prodllct~.were 1.1/-1.50% 1.38-2.15 % and 1.58-2.45% of the
samples weight respectively. Afterward. the total nitrogen element concentration in the upper, middle and
lower layers of tapioca waste products were 0.92-1.15% 1.12-1.45 % and 1.14-1.69% of the samples
weight respectively. The tapioca wa~.teprodllcl~' which col/telll of P alld N elemenls can be used for ferlilizer
