“…However, the common limitation of these reagents are poor selectivity. Revanasiddappa 15 recently reported the use of trifluoperazine hydrochloride as a new selective reagent for the spectrophotometric determination of Tl(III). However the dependence of the method on the oxidation of the reagent by Tl(III) to form a red-colored radical cation make the method amenable to interference from many oxidizing and reducing agents, even at comparable concentration levels.…”

A new sensitive chromogenic reagent, 9,10-phenanthaquinone monoethylthiosemicarbazone (PET), has been synthesized and used in the spectrophotometric determination of Tl(III). In HNO3, H2SO4 or H3PO4 acids, PET can react immediately at room temperature with Tl(III) to form a red 2:1 complex with a maximum absorption at 516 nm. The different analytical parameters affecting the extraction and determination processes have been examined. The calibration curve was found to be linear over the range 0.2 -10 µg cm -3 with a molar absorptivity of 2.2 × 10 4 dm 3 mol -1 cm -1 . Sandell's sensitivity was found to be 0.0093 µg cm -2 . No interference from macroamounts of foreign ions was detected, except for Pd(II). However, Pd(II) does not affect the determination process, because its complex with PET has its λmax at 625 nm. The proposed method has been applied to the determination of Tl(I and III) in synthetic and natural samples after separation by flotation (in oleic acid/kerosene) and solid-phase extraction (on polyurethane foam) techniques. The two methods were found to be accurate and not subject to random error, but solid-phase extraction was preferred because it is cheap, simpler and there is no contamination risk coming from flotation reagents.

“…2-(Quinolin-8-yloxy)acetohydrazones and their cyclized 1,2,3-thiadiazole and 1,2,3-selenadiazole derivatives have anti-amoebic activity against Entamoeba histolytica [13]. Hydrazone ligands serve as extracting agents in spectrophotometric estimation of some ions and species in pharmaceutic formulations [14] as long as it's utilization in treatments of wastewater and catalytic processes [15]. furthermore, azo compounds have an increased attention from researchers [16].…”

ABSTRACT. Novel azo-acetohydrazide complexes ofwith 2-hydroxy-5-((4-nitrophenyl)diazenyl)benzylidene)-2-(p-tolylamino)acetohydrazide have been prepared. All the compounds were analytically and spectroscopically characterized by various techniques. The data of molar conductance indicated the prepared complexes are nonelectrolyte in nature except complexes (10) and (11). The spectroscopic data point out that the behavior of ligand towards metal ions are neutral or monobasic bidentate, and dibasic tridentate ligand linked to the metal ions through oxygen atom of ketonic or enolic carbonyl group, azomethine nitrogen atom and/or deprotonated phenolic group forming either octahedral or tetragonally distorted octahedral geometry. X-ray powder diffraction analysis of complexes (2) and (3) indicate that the complexes are crystalline in nature and have monoclinic structures. The microbicides activities of all compounds evaluated by well diffusion method versus Escherichia coli and Aspergillus niger at different concentration. The bioactivities data elucidated that as the concentration of the tested solutions increases the activities increase.

“…The literature survey reveals that a number of analytical methods for detection of this drug individually or in combination with other drugs have been used including, indirect atomic absorption spectrometry [4], potentiometry [5], reverse phase high performance liquid chromatography (RP-HPLC) [6][7][8][9][10][11][12][13], solid-phase extraction-high performance liquid chromatography (SPE-HPLC) [14], liquid chromatography -mass spectrometry / mass spectrometry (LC-MS/MS) [15] densitometry [16] and spectrophotometry [17][18][19][20]. Also, this drug was proposed as a chelating agent for the determination of some metal ions like Cr +6 [21], Tl 3+ [22], Fe 3+ [23] ions. In general, one can refer to the analytical applications of the reactions of phenothiazine derivatives with some metal ions through access to the best article published an article in 1999 [24].…”

A green method was established for the mutual determination of the drug trifluoperazine hydrochloride (TFPH) and vanadium (V) in real samples by coupling the cloud point extraction with UV-Vis spectrophotometry. The method was based on the formation of the colored V (V)-TFPH complex in acidic medium followed the extraction of the complex by using the surfactant Triton X-114 as an extracting medium. The surfactant-rich phase extracted was dissolved in a small volume of solvent and both the drug TFPH and V (V) ions determined by spectrophotometry at maximum absorption wavelength of 476 nm. Most parameters which impact on the extraction efficiency and detection for both target analytes were optimized. Under the optimum conditions established, the preconcentration factor was found to be of 50 fold making Beer's law obeyed in the concentration range of 2-80 µg mL -1 (r = 0.9999) for the determination of TFPH and 0.5-10 µg mL -1 (r = 0.9995) for vanadium (V), giving the detection limits of 1.21 and 0.113 µg mL -1 respectively. The mean recovery percentage of 98.94±2.19 % (in blood serum) and 99.43±1.40 (in tap water); the precision (RSD %) ranged between 0.48-3.40 % and 0.45-1.49 were obtained for TFPH and V (V) ions respectively. The proposed method was employed for the determination of TFPH in pharmaceuticals and the spiked serum samples, while a V (V) ion was determined in black pepper samples.
