“…Considering the widespread use of thorium and its toxic properties, the development and improvement of analysis methods for the determination of thorium are vital. Therefore, many techniques have been used for the determination of thorium, including nuclear techniques, inductively coupled plasma/mass spectrometry, electrochemistry, ion chromatography, X‐ray fluorescence and so on . Among these analysis methods, fluorescence detection is a simple, rapid, highly selective, and low‐cost method for thorium ion determination.…”

A novel fluorescent sensor based on tetraphenylethene (TPE) modified with 2,6-pyridinedicarboxylic acid (PDA) that shows aggregation-induced emission (AIE) characteristics for thorium recognition with remarkable fluoresence enhancement response has been synthesized. This sensor is capable of visually distinguishing Th(4+) among lanthanides, transition metals, and alkali metals under UV light. Th(4+) can be detected by the naked eye at ppb levels owing to the AIE phenomenon. The sensor showed high selectivity for Th(4+) compared to all other metals tested, and this recognition displayed good anti-interference qualities. This study represents the first application of a AIE fluorescence sensor in actinide metal recognition and it has potential applications in environmental systems for thorium ion detection.

Although only a slightly radioactive element, thorium is considered extremely toxic because its various species, which reach the environment, can constitute an important problem for the health of the population. The present paper aims to expand the possibilities of using membrane processes in the removal, recovery and recycling of thorium from industrial residues reaching municipal waste-processing platforms. The paper includes a short introduction on the interest shown in this element, a weak radioactive metal, followed by highlighting some common (domestic) uses. In a distinct but concise section, the bio-medical impact of thorium is presented. The classic technologies for obtaining thorium are concentrated in a single schema, and the speciation of thorium is presented with an emphasis on the formation of hydroxo-complexes and complexes with common organic reagents. The determination of thorium is highlighted on the basis of its radioactivity, but especially through methods that call for extraction followed by an established electrochemical, spectral or chromatographic method. Membrane processes are presented based on the electrochemical potential difference, including barro-membrane processes, electrodialysis, liquid membranes and hybrid processes. A separate sub-chapter is devoted to proposals and recommendations for the use of membranes in order to achieve some progress in urban mining for the valorization of thorium.

Simultaneous anodic stripping voltammetric determination of lead and cadmium with a carbon paste electrode modified by tributyl phosphate

et al. 1998

Abstract.A chemically modified carbon paste electrode was prepared by incorporating quantities of tributyl phosphate (TBP) directly into the paste mixture. In the presence of 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone (PMBP), trace lead and cadmium in acetic acid-acetate medium can be preconcentrated on the electrode. The method showed good linearly for 1.0 x 10 -s -8.0 x 10 .7 mol.L -1 lead(II) and for 5.0 x 10 .8 -2.0 • 10 .6 mol.L -1 cadmium(II). Many common metal ions have no or little effect on the determination of lead(II) and cadmium(II). The electrode was verified by the determination of trace lead(II) and cadmium(II) in waste water and human hair samples.
