Selective micelle mediated extraction of thorium from uranium and some lanthanides and its determination by inductively coupled plasma-optical emission spectrometry

Atomic spectrometry update: review of advances in the analysis of metals, chemicals and materials

“…Mortada et al investigated an eco-friendly alternative for the extraction and separation of Th from U and lanthanides in wastewater and phosphate rocks prior to ICP-OES measurement. 208 Morin formed a complex with Th 4+ at pH 2-4 that quantitatively extracted it into the surfactant-rich phase in the presence of 0.1% (v/v) Triton X-114 and 0.1% (w/v) KI at room temperature. The analytical range and detection limit compared favourably to other cloud point extraction procedures for Th, with an enrichment factor of 49.5 for a 50 mL sample and a recovery of at least 95% in Th-spiked samples.…”

“…Applications of the analysis of ceramic cultural heritage samples Pb,207 Pb/204 Pb,207 Pb/206 Pb, 208 Pb/204 Pb,208 Pb/206 Pb were measured on the glazed coatings of each sample. No mass bias correction was necessary.…”
