On site separation of inorganic forms of thallium and arsenic in sea water systems followed by ICP-MS determination

Abstract

Reduction of Tl(iii) and oxidation of As(iii), which are unstable speciation forms, start just after sampling as a result of disturbed chemical equilibrium.

Anodic Stripping Voltammetric Procedure of Thallium(I) Determination by Means of a Bismuth-Plated Gold-Based Microelectrode Array

“…Various analytical methods have been proposed to determine thallium ions. The most common spectroscopic techniques have been used, such as atomic absorption spectrometry ET–AAS [ 17 , 18 , 19 ], HG–AAS [ 20 ], graphite furnace atomic absorption spectrometry GF–AAS [ 21 ], atomic emission spectrometry ICP–OES [ 22 , 23 , 24 ], and a very sensitive inductively coupled plasma mass spectrometry ICP–MS [ 25 , 26 ].…”
