In this paper, alcohol (methanol, ethanol, n-propanol)-water system was used as solution for the desorption of Acid Orange 7 (AO7), Ponceau 2R and Rhodamine B (RhB) from dye-loaded carbon (XC-72). Excellent degradation efficiency was obtained (desorption efficiency reaches 77.35%, 85.60%, 96.86% for Ponceau 2R, AO7 and Rhodamine B, respectively) and it was significantly influenced by alcohol content and the length of carbon chain in alcohol (hydrophobicity). In addition, desorption kinetics was fitted by a second-order desorption model, and the desorbed quantity at equilibrium (qe) and rate constant (kd) were calculated, respectively.

Kinetics Of

The kinetics of alkaline cleavage of o-nitrobenzyltrimethylsilane were examined in aqueous dioxane media. At high water concentrations, increases in solvent polarity retard the cleavage, as required by a mechanism involving charge dispersion in the transition state. At high dioxane concentrations, solvent polarity increases are accompanied by increases in the rate of reaction, a result which may reflect association between the solvent components.
