Aggregation of an anionic azo dye with conventional cationic surfactants in premicellar region: A conductometric study
The interaction of Congo Red CR with a series of Alkyltrimethylamoniumbromide CnTAB, N-hexadecylpyridinium bromide CPB and N-hexadecylpyridinium CPC were investigated using conductometry technique. It was observed that the formation of dye-surfactant ion pairs takes place at surfactant concentration far below the critical micelle concentration of the individual surfactants. Aggregation was refl...
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...
متن کاملEffect of bromide and iodide on chloride methodologies in plasma or serum.
The effect of adding known amounts of bromide and iodide to a plasma pool an several methodologies for measuring chloride ion has been studied. Methods evaluated were coulometric, colorimetric, and ion-specific electrode. Three different types of electrodes were evaluated in order to assess any improvements which might have been made in recent years. The older electrode methodology showed an ex...
متن کاملCoulometric Titration with Electrogenerated +2 Tin Determination of Iodine, Bromine. and Various Oxidants via Iodometry
Although the roster of coulometric titrations no\\' includes many reactions of classical titrimetry'. the lIse of cl,ectrogeneratecl +2 tin as a coulometric titrant has not previously been reported. We have found that in an acidic bromide medium +4 tin (probably SrlBr6-2) is reduced to the' +2 state (probably SnBr4-2) with 100% current efficiency' at a gold cathode. The formal potential of the ...
متن کاملSelective Membrane Electrode for Bromide Ion Based on Aza Pyrilium Ion Derivative as a new Ionophore.
A highly selective electrode for Bromide ion based on aza pyrilium derivative as an excellentionophore is described.The sensor exhibits a good linear response with a slope of ( 60±1 ) mV per decadeover the concentration range of ( 1×10-3 – 9×10-6 M ) , and a detection limit of ( 3×10-6 M ) of Bromideions .The electrode response is independent of pH in the range of(4.0 –9.5).Selectivity coeffici...
