Conclusion The use of SPE procedures has been growing in the past few years due to their
advantages offered for trace element determinations, namely conservation of species, good …

An overview of the strategies adopted in flow analysis towards cleaner analytical methods is
presented. The discussion deals with reagentless procedures, replacement of hazardous …

The synthesis and characterization of Mn (II), Fe (III), Co (II), Ni (II), Cu (II), Zn (II), Cd (II), Pd
(II) and UO2 (II) chelates of 1-(2-thiazolylazo)-2-naphthalenol (TAN) were reported. The …

An overview is presented on thiazolylazo dyes and their analytical applications in the
determination, preconcentration or separation of trace metal ions. The article summarizes …

A novel efficient Hg (II) adsorbent was prepared by impregnating 1-(2-thiazolylazo)-2-
naphtol (TAN) onto Amberlite XAD-4 resin beads. Batch sorption experiments were carried …

Solid-phase extraction (SPE) is an effective tool for the preconcentration of trace elements
and their separation from various sample constituents. Octadecyl and other alkyl-bonded …

Abstract A new thiazolylazo structure, 1-[(5-(3-nitrobenzyl)-1, 3-thiazol-2-yl) diazenyl]
naphthalen-2-ol (NBnTAN), has been synthesized for the first time. The geometric …

A spectrophotometric procedure for the simultaneous determination of zinc (II) and copper
(II) in a mixture using diethyldithiocarbamate (DDTC) as ligand has been described …

The charge transfer interaction between 1-(2-Thiazolylazo)-2-naphthol (TAN) and aromatic
nitro compounds were studied spectroscopically in methanol. These experimental and …

In this work, a new solid phase spectrophotometric method in association with flow injection
