Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy, 85(1), 223-234 (2011-10-25)
Few novel 4-aminoantipyrine derived Schiff bases and their metal complexes were synthesized and characterized. Their structural features and other properties were deduced from the elemental analysis, magnetic susceptibility and molar conductivity as well as from mass, IR, UV-vis, (1)H NMR

In this work, a new method based on the combination of dispersive liquid-liquid microextraction (DLLME) with microvolume spectrophotometry has been developed as a greener and miniaturized alternative to the 5530 APHA standard method for determining phenols in water and wastewater.
Qihui Wang et al.
Journal of hazardous materials, 186(2-3), 1076-1081 (2010-12-21)
In this work, the immobilization of 4-aminoantipyrine onto bentonite was carried out and it was then used to investigate the adsorption behavior of Cr(III), Hg(II) and Pb(II) ions from aqueous solutions. The separation and preconcentration conditions of analytes were investigated
