Diacetylmonoxime Isonicotinoyl Hydrazone is new chromogenic reagent for the simultaneous determination of Gallium (III) and Aluminium(III). The reagent gives greenish yellow color in sodium acetateacetic acid buffer medium with the metal ions. The maximum absorbance at 377 and 367 nm for Ga(III) and Al(III) respectively. The molar absorptivities of Al(III) and Ga(III) are 2.69 x 10 and 3.17 x 1...

objective(s):skin extracellular matrix, which contains type i and type iii collagens, is involved in skin development. the aim of this study was to investigate type iii collagen distribution pattern as well as its changes during pre and post-natal skin morphogenesis in rats. materials and methods: ventral skins of wistar rat embryos at different stages from 10 to 20 gestational day (e10-e20) an...

A new polyvinyl choloride (PVC) membrane sensor for cerium(III) was prepared based on 4,13-didecyl-1,7,10,16-tetraoxa-4,13-diazacyclooctadecane (kryptofix22DD) as an ionophore. The sensorexhibites a linear concentration range of 1.0×10-6 to 1.0×10-1 M, with aNernstian slope of 18.0±1.0 mV/decade, and a detection limit of 9.7×10-7M. It has a fast response time (5 s) and can be used for two month...

A PVC membrane electrode based on 1-[({[(butylsulfunyl)carbothioyl]disulfanyl} carbothioyl)sulfanyl]butane as a suitable ion carrier for determination of lanthanum(III) ion was prepared. This electrode revealedsuch a good selectivity toward La3+ ion over a wide variety of other metal ions. Some experimental parametersuch as membrane composition, nature, and amount of plasticizer, the amount of ...

Polyvinyl alcohol/ glycerin- magnetic iron oxide nanoparticles (PVAGLPs) have been synthesized successfully by hydrothermal method. The as-prepared samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared spectra (FTIR). The adsorbed activities of the polyvinyl alcohol/ glycerin- magnetic iron oxide nano particles (PVAGLPs) were ca...
