“…The amino resin was diazotized by suspending in 350 mL of an ice-water mixture and treated with 1.0-mL portions of 1.0 mol L −1 HCl and 1.0 mol L −1 NaNO 2 solutions with continuous stirring until the reaction mixture began to turn starch-iodide paper a permanent dark blue. 35 The diazonium resin was filtered off, washed with ice-cold water, and reacted with 11.4 g of APPT (dissolved in 250 mL of methanol) at 0-5 • C for 24 h. Amberlite XAD-2-N=N-APPT resin was filtered off, washed, and air dried.…”

“…Various thiosemicarbazones and phenyl-3-thiosemicarbazones have been widely used as spectrophotometric and spectrofluorimetric reagents for metal ions. 35 Among these, 2-acetylpyridine-4-phenyl-3-thiosemicarbazone (APPT) ligand is more suitable for metal chelation. 36 APPT has been used as a spectrophotometric reagent for the determination of Cu(II) ions 37 but APPT functionalized solid phase has not been screened for solid phase extractive preconcentration of metal ions.…”

“…HPLC methods are simple, and the sensitivity required is achieved by using appropriate chromogenic reagents. Useful HPLC separations and quantitative analyses of metal ions have been achieved with the ligands 2-piconaldehyde-4-phenyl-3-thiosemicarbazone, 2-(2-quinolinylazo)-4-methyl-1,3-dihydroxybenzene, tetra-(4-methylphenyl) porphine, tetra-(4-dimethylaminophenyl)porphyrin, pyridine-2-acetaldehyde benzolhydrazone, bis(ethoxyethyl)dithiocarbamate, 2-thiophenaldehyde-4-phenyl-3-thiosemicarbazone, 2-pyrrolaldehyde-4-pheny l-3-thiosemicarbazone, and 2-acetylpyridine-4-phenyl-3-thiosemicarbazone [28][29][30][31][32][33][34][35][36][37][38][39][40][41][42].…”
