On-line preconcentration and vapor generation of scandium prior to ICP-OES detection

Vapor generation – atomic spectrometric techniques. Expanding frontiers through specific-species preconcentration. A review

“…Another interesting approach has been reported by Yuan et al [93].There is almost no combination of CPE with cold vapour atomic fluorescence spectrometry (CVAFS) for Hg determination. This is probably because of the foam produced during the vapour mercury generation process in the medium of surfactant, which may interfere with the determination of Hg and then inhibit the application of CPE for Hg determination.…”

“…Some other transition and noble metals have been tested with THB-based reactions, and volatile species were generated expanding VG applications [9][10][11]. In spite of the sensitivity and selectivity achieved, different sample pretreatments are often needed in order to either adequate it for the VG process, eliminate interferences (sample clean up) or preconcentrate analyte(s) [6,[12][13][14][15].…”

Atomic spectrometry update: review of advances in atomic spectrometry and related techniques

“…Cerutti et al 75 have developed an on-line method for CVG of Sc by acidified (10% v/v HCl) NaBH 4 after preconcentration onto a minicolumn of activated carbon at pH 7. The volatile Sc compound was then swept into an ICP-AES spectrometer to give an enhancement factor of 240 and an LOD of 4 µg L -1 .…”

Isophtalic acid terminated graphene oxide modified glassy carbon nanosensor electrode: Cd2+and Bi3+analysis in tap water and milk samples

“…Also, these values were very good as comparison with the literature. [58,59] The selectivity of the method for the determination of various metal ions was evaluated for various ions including Bi 3+ and Cd 2+ solutions. In this study, interferences of equimolar concentrations of Hg 2+ , Fe 2+ , Cu 2+ , and Zn 2+ were studied at different pHs.…”
