title: Determination of trace amounts of mercury in water by neutron activation analysis with lubricating base oil as extractant.
abstract: This paper deals with a convenient method in the determination of trace amounts of mercury in water. After being irradiated with neutrons, water sample was treated with 7.0M HCIO4 solution and mercury was extracted with lubricating base oil. In such a simple operation, the sensitivity can reach 10(-8)g Hg/4ml H2O.
