Analytical applications of thiosemicarbazones and semicarbazones

A Rapid and Simple Spectrophotometric Determination of Traces of Chromium (VI) in Waste Water Samples and in Soil samples by using 2-Hydroxy, 3-Methoxy Benzaldehyde Thiosemicarbazone (HMBATSC)

“…The formation constant of the soluble complex was calculated from the results obtained in Job's method as 6.95x10 4 .…”

“…Among various organic reagents containing sulphur and nitrogen as donor atoms, thiosemicarbazones occupy a unique place. Thosemicarbazones [2][3][4][5][6][7][8] were the important classes of reagents widely employed for the sepectrophotometric determination of metal ions.…”

A Rapid and Sensitive Extractive Spectrophotometric Determination of Palladium(II) in Synthetic Mixtures and Hydrogenation Catalysts Using Pyridoxal-4-phenyl-3-thiosemicarbazone

“…Recently, there has been a rapid growth in the popularity of sulfur-bearing ligands, such as thio-and phenylthiosemicarbazones, in analytical chemistry, for the spectrophotometric and extractive spectrophotometric determination of metal ions. [1][2][3] The metal chelates of these sulfur and nitrogen-containing organic reagents find a wide range of applications in medicine 4 and agriculture. 5 A thorough literary survey has revealed that many thiosemicarbazones are available for the extractive spectrophotometric determination of palladium(II).…”

SIMULTANEOUS SPECTROPHOTOMETRIC DETERMINATION OF Cu(II) AND Co(II) USING 5-BROMOSALICYLALDEHYDE THIOSEMICARBAZONE BY PARTIAL LEAST SQUARES REGRESSION METHOD

“…The wide use of thiosemicarbazones in the inorganic analysis has been reviewed in detail by Suparupu et al, Grag and Jain, Grag and Sing usually using spectrophotometric technique. [2][3][4][5][6][7][8][9][10][11] Few reports have been published on the simultaneous determination of Cu(II) and Co(II) in different samples. [12][13][14] Until now, there is no scientific paper in the application of 5-bromosalicylaldehyde thiosemicarbazone (5-BSAM) for simultaneous determination of these ions.…”
