Multi elements analysis of groundwater in Ujung Lemahabang

Determination of multi elements in groundwater collected from Ujung Lemahabang Muria peninsula have been carried out. The propose of this research is to justify neutron activation analysis (NAA) method using ammonium pyrrolidine dithio carbamate (APDC) as complexing agents. Groundwater was collected from 3 sampling sites in Ujung Lemahabang area. The results of analysis showed that the concentration of As, Cr, Co, Hg, Mn, Sb, Sc, and Zn obtained in the range 6.4 - 8.7; 0.24 - 1.6; 1.14 - 2.51; 2.06 - 6.86; 5.12 - 13.55; 4.52 - 12.43; 0.08 - 7.49; 12.28 - 48.16 ppb, respectively. This method is suitable and can be applied to determine trace elements in natural water. (author)
