Kinetic study on the electrodecolorization of C.I. Acid Yellow 23
The electrocoagulation (EC) is a simple and efficient method for the treatment of many water and wastewaters.The kinetics of decolorization of Acid Yellow 23 by EC using iron electrodes was studied. Theelectrodecolorization rate follows pseudo-first order kinetic with respect to the AY23 concentration havingkapp= 5.65 cm min-1 at T= 295 K. The rate equation is as follows:ln [AY23]t – ln [AY23]0...
متن کاملThe zwitterion (23′E)-(23R,25S)-23-[1-(oxidoiminio)ethyl]-5β-spirostan-3β-yl acetate
The title steroidal compound, C(31)H(49)NO(5), resulted from the selective oximation of (23R)-23-acetyl-sarsasapogenin acetate. One- and two-dimensional (1)H and (13)C NMR spectra, as well as IR data, are in agreement with the presence of a ketoxime group at C-23. However, recrystallization in slightly acidic media affords the title compound in the rare zwitterionic oxime form, as a consequence...

متن کاملMechanical Properties and Function of Pericardium E - 23 - 638
This paper considers the effects of the pericardium on a mechanical model of the heart. The model, based on the theory of large elastic deformation, makes use of experimental data for the pericardium reported herein. INTRODUCTION The pericardium is the tough fibrous sac enclosing the lean of most vertebrates, including man. It serves to .told the heart in a fixed position and to isolate and xot...
متن کاملIFT 94/23 TESTING THE WWγ COUPLING AT e + e − COLLIDERS ∗
The production of single photons plus missing energy at future ee colliders can provide a testing ground for non-standard WWγ couplings. We show that even with conservative estimates of systematic errors there is still considerable sensitivity to anomalous couplings. In spite of many experimental successes certain aspects of the standard model still await for direct tests. Among them is the non...
