Abstract
Sensitive and Selective Spectrophotometric Assay of Lead in Aqueous Solution
Highlights
The determination of lead is very important from both the health and pollution points of view
Flame atomic absorption spectrometry (FAAS) is a more frequently used technique due to its simplicity and lower cost, this method has a limited sensitivity for lead so a preconcentration step is often required to improve the detection limit (Vinas et al, 1997)
Other detection techniques are used such as inductively coupled plasma mass spectrometry (ICP-MS) (Hung et al, 1999)
Summary
The determination of lead is very important from both the health and pollution points of view. From the above literature survey of lead; this paper reports a spectrophotometric method using zincon reagent for a fast, sensitive and selective assay of lead traces in aqueous solution. This solution is prepared by mixing 50 ml of (0.1 M boric acid and KCl) and 34.6 ml of NaOH, the volume is completed to 100 ml with double distilled water.
