Extraction and spectrophotometric determination of lead(II) with pyridine-2-acetaldehyde salicyloylhydrazone

This review of the 1995 literature summarizes analytical techniques for the determination of chemical species in natural waters, wastewater, and drinking water. The emphasis is on chemical species of interest to environmental professionals. The review is organized into four main sections. The first section describes New Chemical Methods for determination of aqueous pollutants, whereas the second section describes New Biological Methods.

“…Dithiazone [14], diethyldithiocarbamate [15][16][17], arsenazo III [14], 4-(2-pyridylazo)-resorcinol (PAR) [18], malachite green [19], butylrhodamine-B [20], xylenol orange [21], 2-(2-thiazolylazo)-pcresol, dithiodibenzoic acid [22], dithiodibenzoic acid iodideethylene violet-polyvinyl chloride [23], and a copolymer consisting of protoporphyrin disodium salt and acrylamide [24] were suitable for the trace analysis of lead in clinical samples due to their low detection limit. Dibromo-p-methylsulfonazo [25] was sensitive, but Ca 2+ and Mg 2+ , which exist in clinical samples were reasonable amounts, interfere with the determination of lead and require prior separation with potassium iodide-methylisobutylketone extraction.…”

“…[6][7][8][9][10] Lead and its compounds are hazardous because the poison is cumulative and its toxic effects are many and severe 11 . Many spectrophotometric methods [12][13][14][15][16] for the determination of trace amounts of lead in complex materials have been reported. Most methods for both nickel and lead have their particular sensitivity and are subject to various interferences and limitations.…”

Spectrophotometric studies have been made to investigate the reaction of Nickel and Lead with 2-carboxy-2'-hydroxy-5'-sulfoformazyl-benzene (zincon) in 50%(v/v) ethanol-water at 25 degrees C and an ionic strength of 0.1 M NaClO4. A complete picture of the complexation equilibria in the pH range (4.2-12.0) for nickel and (1.9-11.5) for lead are presented. Simple, rapid, selective and sensitive methods for the spectro-photometric determination of nickel and lead has been developed based on the color reaction of their complexes with zincon. The methods allow the determination of 4.69 microg mL(-1) of nickel at pH = 6.3 (lambdamax = 665 nm) and 10.3 microg ml(-1) of lead at pH = 5.6 (lambdamax = 610 nm). The apparent molar absorptivities were epsilon = 1.3 x 10(4) L mol(-1) cm(-1) for nickel and epsilon = 0.6 x 10(4) L mol(-1) cm(-1) for lead. The interference of a large number of foreign ions and complexing agents has been studied. Thiosulphate, as masking agent allows the simultaneous determination of nickel and lead in the presence of high concentrations of copper. Ascorbic acid, sodium cyanide and or sodium fluoride provide the elimination of many other interferences. The methods have been applied successfully to the simultaneous determination of nickel and lead in an aluminium and non-ferrous alloy.
