Abstract
The method of incorporating in-situ pre-concentration technique via multiple injections followed by electrothermal atomic absorption spectrometry (ETAAS) is described for the direct determination of lead at sub-ppb levels in secondary coolants of pressurized water reactor (PWR). Prior to ETAAS measurement, water samples were concentrated by means of multiple injections (9×90 ml) and evaporation in a pyrocoated graphite tube. Optimization of the in-situ pre-concentration via multiple injections with ETAAS analysis was investigated. The feasibility of the proposed method was tested for direct determination of lead in secondary coolants of pressurized water reactor. A SRM 1643c certified reference water sample has been used for quality control. The result are in good agreement with the certified value. By the use of 0.81 ml sample volume 0.012 ppb detection limit was obtained.
