Direct Spectrophotometric Determination of Lead (II) in Industrial Samples using 1, 3-Benzenediamine, N, N'-bis(2-furanylmethylene) in Presence of Surfactant

Abstract

Schiff's base are one of the excellent chelating agents that used for the spectrophotometric determination of metal ions. It was observed that 1, 3-Benzenediamine, N,N'-bis(2-furanylmethylene) (BDFM) formed a brown colored complex with lead (II) at 620 nm. Lead (II) was chelated with the Schiff's base (BDFM) in acidic medium at pH = 3.5 using acetate buffer in presence of sodium laureth sulfate (SLS) as a surfactant. The effect of time, temperature and foreign ions were studied. The stoichiometric composition of the formed complex was found to be 1:2 (metal: ligand) by Job's method of continuous variation. Beer's law was obeyed in the range of 10-110 µg mL-1 with molar absorptivity 10.16×10 3 L mol-1 cm-1. The proposed method was applied for the determination of lead in gasoline, solders, gutters and wastewater.

Removal of Cobalt Metal Ion from Aqueous Solution using Punica granatum Stem Powder as Biosorbent

“…PGSP before cobalt metal ion adsorption shows FTIR data as, hydroxyl (OH) at 3758. resulting for carbohydrate. [45] PGSP after cobalt metal adsorption shows variant frequency bands of 479.61 and 619.49 cm -1 for the presence of cobalt ion peak associated with the complex formation with phytochemicals and hence proved that PGSP has an efficient capacity to adsorb cobalt metal ions. show in Figs 7A and B.…”
