Aquation of (Dimethyl sulphoxide)pentaamminecobalt(III) in Aqueous Cetyhrimethylammonium Bromide Solutions
نویسنده
چکیده
The rate of aquation of [Co(NH3)s (DMSO)] Bra was measured in solutions containing the surfactant cetyltrimethylammonium bromide (CTAB) over the concentration range 9.55 x 10-4 mol dm-3 to 0.450 mol dm-3• This large change in CTAB concentration affected the rate very little and no significant amounts of Co(NH3)sBr+ were formed .. It was concluded that, if Brcounterions were concentrated in the microregions around the positively charged CTAB micelles, then there was no corresponding increase in the formation of Co(NH3)s (DMS0)3+. Brion-pairs in this region with subsequent Co(NH3)sBr+ formation.

Details are given of the v ( S O ) ~ ~ ~ ~ stretching (dmso = dimethyl sulphoxide), v,(SO,), v,(SO,), and v,(SO,) regions of the Raman spectra of SO,-dmso mixtures at 293 K and sub-ambient temperatures. Analysis of the v( SO)dmso region, which contains at least seven component bands, provides evidence of several component species. Bands at 1 067,l 057, and 1 044 cm-l are due to monomers and ass...

Autograft is gold standard treatment for peripheral nerve repair up to now. Eggshell membrane (ESM) as nerve guide channel effectively enhances nerve regeneration. Dimethyl sulphoxide (DMSO) has anti-inflammatory and anti-oxidant properties. The aim of this study was to evaluate the effect of DMSO+eggshell membrane guide channel on sciatic nerve regeneration in rats. Thirty two adult male rats ...
متن کاملRemoval of bromide from aqueous solutions using the UV/ZnO process based on the multivariate analysis model
Background: Bromide is found naturally in groundwater and surface water. The rapid growth of industrial activities, drainage of surface runoff, and use of methyl bromide in pesticides has increased bromide discharge to the environment. Disinfection of water-containing bromide causes the creation of additional products of organo-halogenated that are considered cancer-causing agents. In...
