“…The reagent absorbance at the maximum absorbance of metal complex was further suppressed using suitable concentration of reagent as blank and further absorbance measurements were made at 370 nm. The absorption spectra in the 300-600 nm range for 3,4-DHBINH and Pd(II)-3,4-DHBINH complex 45 were recorded. The formation of the 380 nm band in the spectra must be connected with the chelate formation between Pd(II)-3,4-DHBINH.…”

The synthesis and spectral characterization of benzyloxy-benzaldehydethiosemicarbazone (BBTSC) and the study of antibacterial activity of ligands BBTSC, 3,4-dihydroxybenzaldehydeisoni- cotinoylhydrazone (3,4-DHBINH) and their transition metal complexes was studied. The composition of the metal complexes was also evaluated by using Job’s method, molar-ratio method and Asmus’ method. The antibacterial activities of BBTSC, 3,4-DHBINH and their complexesi.e., Cu(II)-BBTSC, Pd(II)-BBTSC, Cr(VI)- 3,4-DHBINH, Ti(IV)- 3,4-DHBINH and Pd(II)-3,4-DHBINH were studied against two gram positive bacteria and two gram negative bacteria. Antibacterial activities were evaluated by agar cup well method with the help of Luria Bertoni plates.

The simple, rapid spectrophotometric method for palladium(II) ions determination using a new analytical reagent is described. The interaction of Pd(II) ions with a reagent, of the class of azolidones, 4-(N′-(4-imino-2-oxo-thiazolidine-5-ylidene)-hydrazino)-benzoic acid, in water medium results in the formation of a complex. The Pd(II)-p-ITYBA complex shows maximum absorbance at a wavelength of 450 nm. The molar absorptivity is 4.30 × 103 L·mol−1·cm−1. The optimal pH for complex formation is 7.0. The developed method has a wide linearity range of 0.64–10.64 µg·mL−1 for Pd(II). The detection limit is 0.23 µg·mL−1. It was found that Co(II), Ni(II), Zn(II), Fe(III), Cu(II), Al(III), and many anions do not interfere with the Pd(II) determination. The proposed method was tested in the analysis of model solutions and successfully applied for the determination of palladium in catalyst. The obtained results show that this method can be used for serial determinations of palladium in various objects.

Al-Harbi, Dualndashwave rmbeta Correction Spectrophotometric Determination of Palladium Ions using Neothorin, Journal of Taibah University for Science (2015), http://dx.Abstract A simple and low cost method has been developed and validated for the determination of trace palladium (II) ions in water and fertilizer samples. The method was based on the reaction of palladium (II) ions with the reagent neothorin (2-(2-Arsonophenylazo) chromotropic acid disodium salt) the formed complex shows an absorption maximum at 567 nm (λ max ) in Britton -Robinson (BR) buffer (pH 2).The corrected absorbance of the formed complex at λ max was obtained employing β-correction spectrophotometric method. Beer's -Lambert law and Ringbom , s plots of the colored palladium reagent complex were obeyed in the concentration range 0.05 -2.7 and 0.1 -2 µg mL -1 palladium (II) ions, respectively with a relative standard deviation in the range of ±1.3-2.1 %. The limits of detection (LOD) and quantitation (LOQ) of the procedure were 0.011 and 0.04 µg mL -1 palladium , respectively. The proposed method was applied for the analysis of palladium (II) in spiked tap, mineral and underground water samples . The results of the developed method were compared satisfactorily with the data obtained by the inductively-coupled plasma-mass spectrometric (ICP-MS) method. Statistical comparison of the results of the proposed method with those obtained by the standard method revealed no significant differences in the accuracy and precision. The method offers a simple system coupled with good reproducibility, accuracy, ruggedness and cost effectiveness.
