Sorbent extraction of 4-(2-thiazolylazo) resorcinol (TAR)–metal chelates on Diaion SP-850 adsorption resin in order to preconcentration/separation

Use of natural clays as sorbent materials for rare earth ions: Materials characterization and set up of the operative parameters

“…Extraction resins combine the advantages of high selectivity, typical of solvent extraction, with high efficiency typical of chromatographic separation. In addition, they are characterized by large surface area, require minimal use of organic solvents (and thus are environmentally friendly) and phase separation phenomena do not occur (Soylak and Yilmaz, 2010). Nanostructured materials such as nanotubes are advantageous for their large specific surface area, excellent mechanical strength, and high chemical stability http://dx.doi.org/10.1016/j.wasman.2015.09.017 0956-053X/Ó 2015 Elsevier Ltd.

Complex Formation in a Liquid-Liquid Extraction System Containing Co(II), 4-(2-Thiazolylazo)resorcinol and Monotetrazolium Salt

“…[5][6][7][8][9] The complex formation with azo derivatives of resorcinol via phenolic oxygen, azo nitrogen and thiazolyl or pyridylazo nitrogen, gives colored chelates with metal cations. [10][11][12][13][14][15][16][17][18][19] Tetrazolium salts are used as reagents for the extraction-spectrophotometric determination of metals, e.g. Mo(VI), W(VI), Ge(IV), Tl(III), Nb(V), V(IV), V(V), Ga(III).…”

Development and validation of the simple and sensitive spectrophotometric method of sulphanilamides determination with 4-(2-thiazolylazo)-resorcinol in veterinary preparations

“…TAR was used in ion-exchange liquid [12][13][14][15][16] and thin-layer [17] chromatography for the determination of metals ions in natural and drinking water as well as for electrophoretic determination of metals [18][19][20], in optical [21][22][23] and ionselective [24,25] sensors to determine the metals ions, for obtaining of the sorbents modified by azo reagent for concentration metals ions [26][27][28][29][30].…”
