Pengaruh Suhu, Konsentrasi HNO3 dan NH4OH pada Aktivasi Arang Tempurung Kelapa sebagai Adsorben Radionuklida 131F dan 32 PO.4m.

The study focusses on influence of physical activation (temperature) and chemical activation (HNO3 concentration, NifiON concentration) on coconut charcoal capability to adsorp radionuclide 32P and 1311, in anionic form. The result indicated that physical activation (temperature) gives a significant decontamination factor meanwhile chemical activation (HNO3 and NH.,OH concentration) doesnot provide a significant decontamination factor. The best results is obtained if coconut charcoal is dried at 600'C and reacted with 1, 75 M HNO3. Keywords: Radionuclide, activation, dicontamination charcoal
