Determination of some trace elements in Benghazi city drinking water by flame atomic absorption spectrometry

摘要

The major sources of water supply of Benghazi city is the River Project which is represented in Talhia reservoir where water flows through pipes in the network of water distribution from Talhia reservoir to different positions in the city. In this study we divided the study area into three areas A, B and C according to the distance away from Talhia reservoir. Drinking water samples were collected from twenty six positions of Benghazi city during spring and summer seasons between March and September 2009. These samples were analysed for some trace elements Fe2+, Cu2+, Zn2+ and Mn2+ for aim of comparison trace elements in water of the network with Libyan and WHO drinking water standards. The trace elements Fe2+, Cu2+, Zn2+ and Mn2+ were determined by using a flame atomic absorption spectrometer. All trace elements of the network water samples agree well with Libyan and WHO drinking water standards. Comparison between results of spring season and results of summer season showed some differences in the majority of trace elements.
