Intramolecular hydrogen bonding of azo dyes in aqueous solution.
in 0.1 M ionic strength aqueous solution at 120 for the following: 2,4-dihydroxy4'-nitroazobenzene (I), 2,4-dihydroxy-4'-sulfonateazobenzene (II), and p-(2hydroxy-l-naphthylazo) benzenesulfonic acid (III). The reported values of k231 were 4O X 105, 3.6 X 105, and 3.6 X 106 M-1 sec-1. They attributed the much lower values of k23, for these acids than the value3 k23, 2 X 109 M-1 sec-1 kn,' for th...
متن کاملRemoval of Cationic Dyes from Aqueous Solution using Organomodified Nanoclay
In this work, organomodified nanoclay has been used as the adsorbent for the removal ofbasic blue 41, cationic dye from an aqueous solution. The performance of the organomodified nanoclay was tested in a batch system under varying pH (2–12), adsorbent dosage (0.1–2 g L-1), initial dye concentration (10–60 mgL-1), and contact time (5- 100 min). The best conditions were achieved at pH of 7,...
متن کاملAggregation 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 کاملInvestigation of tetramethylenesulfonated calix[4]resorcinarene interactions with azo dyes in aqueous solution.
The interaction of a macrocycle's aggregates with a guest molecule has special interest due to the double role, both of macrocycle cavity and self-associates, in the binding of the guests. Here, we report on the interactions of nonaggregated methyl-substituted (SCA1) and aggregated penthyl-substituted (SCA2) tetramethylenesulfonated calix[4]resorcinarenes with pH indicators methyl yellow (MY) a...
متن کاملReductive degradation of azo dyes in aqueous solution by zero-valent iron
Kinetics of zero-valent iron remediation of two azo dyes in aqueous solution were investigated. Both show pseudo first-order reaction kinetics. Typical apparent reaction rate constants (k) are 0.70 min"' at 33.3 revolutions per second, k decreases with both increased pH and initial dissolved oxygen content increased over 5 mg l", but increases with both increasing iron conc entration and mixin...
