چکیده

The electrolytic conductivities for C.I. Acid Orange 15 and C.I. Acid Red 97 have been studied. The electrolytic conductivities have been analyzed by Deby HUckel-Onsager theory, The degree of ionization, α, Van’t Hoffs factor, i, and thickness of ionic atmosphere, X –1 . were calculated. Each value diminishes with increasing dye concentration. The dye anion transport number, t, mobility’s, μ were also computed at infinite dilution. The results provide evidence for the presence of interionic attraction and association. Furthermore the kinetics of two acid dyes has been studied using spectrophotometric and conductimetric methods. The former study was carried out at 28°C at different percentage of solvents. The results revealed that the reaction rate was govemed by a pseudo-first order.

Kinetic modeling on photo oxidative degradation of C.I acid yellow 23 by UV/H_2 O_2 process

The kinetic of photo oxidative decolorization of C.I. Acid yellow 23 (AY23) was investigated in UV/ process. The semi-logarithmic of the concentrations of AY23 versus irradiation time were linear, suggesting pseudo-first order reaction. A simple kinetic model is proposed which confirms pseudo- first order reaction. The results indicate that the apparent reaction rate constant is a function of l...

Oil-soluble dyes for marking Spodoptera frugiperda (Lepidoptera: Noctuidae).

Although various biological aspects of Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) have been examined, adult movement and dispersal of this insect pest is not well understood. Release-recapture techniques by using marked insects is a useful approach for dispersal studies; however, the marking technique should not significantly affect insect biology or behavior. Therefore, the ef...
