Elemental analysis of rain－and fresh water by neutron activation analysis

Analysis of rain-and fresh water for trace constitutents is a mandatory part of environmental monitoring.This text gives a survey of neutron activation analysis(NAA) within the framework of current environmental water research programmes.based on the practice developed in co-operation with the Dutch Energy Research Centre at Petten(ECN).While the procedures reported in literature cover obout thirty five elements,our routine procedures of instrumental neutron activation analysis(INAA) is limited to ten to fifteen elements.THe use of some dedicated radiochemical separations(RNAA) adds another six,some of which are speciated as well.Current contributions of NAA to water analysis center on determination and speciation of anionic trace elements,notably Br.I,As,and Se,on the assay of some ultra traces like Ag,Au and Hg and on validation.
