Analisis Aktivasi Neutron (AAN) Logam Magnesium dan Mangan dalam Air PDAM setelah Prekonsentrasi Menggunakan Dietilditiokarbamat

ABSTRACT: Tracer  metal  (ng/g)  elements  in  water  can  be  determined  solely  by  a  qualitative  or  quantitative  analysis  using preconcentration  method.  This method improves the sensitivity  of Neutron Activation Analysis (NAA)  into  part per  billion  (ppb)  levels,  therefore  the  type  and  quantity  of  metal  in  the  water  of  PDAM  can  be  determined. Preconcentration  method was performed  by adding diethyldithiocarbamate  (DDC) into water  sample to produce complex metal sediment. The  sediment  was irradiated inside  TRIGA 2000 reactor in P3TkN for 3 minutes  with the pneumatic tube facilities and  readusing  γ-ray spectrometer.  The result ensures diethyldithiocarbamate  is possible to  apply  in  preconcentrated  method  for  NAA,  the  alkali  and  halogen  disturbance  ions  could  also  be  reduced. Quantitatively, elements in PDAM water  are natrium, aluminium, clorine, zirconium, iodine, calcium, manganese, and magnesium. The magnesium and manganese concentration was 0.1 and 0.06 ng/mL.
Key words: Neutron Activation Analysis, preconsentration, dietilditiokarbamat, magnesium, manganese
