Synthesis of 6-(Phenanthrene-3-yl)-2,3-dihydro-1,2,4,-triazine-3-thione as a New Reagent for the Non-Extractive Spectrophotometric Determination of Cu(II)
A simple, sensitive, and non-extractive spectrophotometric method was developed for the determination of copper (II) using a newly synthesized chromogenic reagent, 6-(phenanthrene-3-yl)-1,2,4,-triazine-3-thione(PhDTT), in Tween 80 neutral surfactant. To synthesize the reagent (PhDDT), amyl nitrite was added to 3-acethylphenanthrene and refluxed for 26 hours to produce 2-oxo-2-(phenanthren-3...
متن کاملSpectrophotometric determination of nickel(II) with 2-hydroxy-3-methoxy- benzaldehyde thiosemicarbazone
2-Hydroxy-3-methoxy benzaldehyde thiosemicarbazone has been synthesized, characterized and its analytical application investigated. It reacts with nickel(II) in aqueous solution at pH 4.0-8.0 and at room temperature to form a yellow coloured ML (1:1) complex with absorption maximum at 410 nm and molar absorptivity 2.05×10 l mol cm. Beer’s law is obeyed in the range of 0.058-2.347 μg ml of Ni(II...
متن کاملA NEW SPECTROPHOTOMETRIC PROCEDURE FOR THE DETERMINATION OF NICKEL (11) USING 6-PHENYL-2,3-DIHYDRO-AS-TRIAZINE-3 –THIONE
A spectrophotometric procedure for the determination of Nickel (??) based on the complex formation with 6-phenyl-2, 3-dihydro-as-triazine-3-thione (PDTT) was developed. A yellow compound forms and is easily extractable by chloroform at pH>6. The mole ratio between Nickel (??) and PDTT is 1:4. The absorbance of the complex obeys Beer's law over the concentration range of 1-7 ug of Ni (??) pe...
متن کامل4-(4’-Nitrobenzylideneimino)-3-methyl-5-mercapto-1, 2, 4-triazole, A New Chromogenic Reagent for Extractive Spectrophotometric Determination of Copper (II) in Pharmaceutical and Alloy Samples
A simple, selective and rapid extractive spectrophotometric method has been developed for the extraction and determination of Cu (II) with 4-(4’-nitrobenzylidene imino)-3-methyl-5-mercapto-1, 2, 4-triazole, (NBIMMT). The reagent (NBIMMT) instantly forms stable orange-red coloured complex with Cu (II) at room temperature and quantitatively extracted in chloroform at pH 6.2. The extracted species...
متن کاملDirect Spectrophotometric Determination of Ni (II) Using 5- Bromo-2- hydroxyl -3-methoxybenzaldehyde-4-hydroxy benzoichydrazone
: A rapid, simple,sensitive and selective direct spectrophotometric method has been developed for the determination of nickel(II) in various real samples. 5-Bromo-2-hydroxy-3-methoxy benzaldehyde-p-hydroxybenzoic hydrazone reacts with Ni(II) forming green coloured soluble complex [ ( Ni(II)-5-BHMBHBH] in basic buffer solution. The maximum absorbance was observed in the pH range 5.5-7.5 and Ni(I...
