TL;DR: A sensitive and selective solid phase extraction procedure for the determination of traces of Cu(II, Zn(II), Pb(II) and Fe(III) has been developed and successfully applied for determination of analytes in real samples.
Journal ArticleDOI
Flame atomic absorption spectrometric determination of copper, zinc and manganese after solid-phase extraction using 2,6-dichlorophenyl-3,3-bis(indolyl)methane loaded on Amberlite XAD-16.
TL;DR: A reversible uptake and elution of metal ions, the influence of flow rates of eluent and sample solution, ligand concentration and amount of surfactant and condition of elution solution was also investigated.
Journal ArticleDOI
Silica-bonded S-sulfonic acid: an efficient and recyclable solid acid catalyst for the synthesis of 4,4′-(arylmethylene)bis(1H-pyrazol-5-ols)
TL;DR: Silica-bonded S -sulfonic acid (SBSSA) is employed as a recyclable catalyst for the condensation reaction of aromatic aldehydes with 3-methyl-l-phenyl-5-pyrazolone as discussed by the authors.
Journal ArticleDOI
Preparation of indolylmethanes catalyzed by metal hydrogen sulfates
TL;DR: In this article, solid acids were developed and applied to the condensation reactions of indole with carbonyl compounds at ambient temperature, and tetra-(indolyl)methanes were obtained by the same authors.
