Determination of thallium in biological and environmental samples

Atomic spectrometry update: review of advances in the analysis of clinical and biological materials, foods and beverages

“…Sample preparation, including pre-concentration and extraction approaches, has been and still is a topic of great interest (Section 3.2). Out of concern for the increasing release of Tl into the environment by human activities, Shi et al 8 provided an overview of current progress for its determination in biological and environmental samples, covering both atomic and molecular spectrometry techniques and a detailed discussion of sample preparation methods. Ibourki et al 9 considered the importance of sample preparation for improving both the LODs and the speed of determinations of chemical elements in food and provided a general overview of both strategies and methods.…”

“…In a comprehensive review (205 references) of the determination of Tl in biological and environmental samples, Shi et al devoted a considerable fraction of the review to sample preparation. 8 Topics covered included, SPE, CPE, and DLLME. On the instrumental side, contributions to the literature were summarised in three tables devoted to detection by (1) AAS, (2) AES and (3) ICP-MS. A fourth table (18 entries) covered molecular spectrometry techniques (colorimetry, fluorimetry and chemiluminescence).…”
