Abstract
A method based on pre-concentration, using electrolysis, has been proposed and used for the improvement of detection sensitivity of mercury ions at ultra-trace level of concentration in an aqueous matrix by laser-induced breakdown spectroscopy (LIBS). The experimental evaluation of this method was carried out on mercury chloride (HgCl2) in triple-distilled water for a concentration range of the element of 0.01–10 mg l−1. A pre-concentration factor of ∼180 was obtained for LIBS detection of mercury emission line at 253.65 nm. The limit of detection (LoD) of ∼0.011 mg l−1 (or ∼11 ppb) for mercury in the water sample was achieved.
