This work studies the removal efficiency of three organic compounds which possess similar charged group but contain different non-polar moieties. The greater removal of compounds with more hydrophobic nature indicates the importance of solute-solvent interactions. Hydrophobic compounds also compete with inorganic anions present in the water matrix. The rejection of hydrophobic moieties from water and thus a favourable positive entropy change in the system by their removal is a crucial driver for the adsorption of organics onto the resin.1 1463 Prediction of Spout Diameter in Gas-Solid Spouted Beds Using Factorial Design of Experiments Approach with the Aid of Advanced Optical Fibre Probe Muthanna Al-Dahhan, Shreekanta Aradhya and Haidar Taofeeq The spout diameter is considered an important hydrodynamic parameter in the design and operation of gas-solid spouted beds. Therefore, the impact of five operating and design variables (solid density, static bed height, particle diameter, superficial gas velocity, and inlet diameter) on the spout diameter have been studied in the present work. The experimental measurements were carried out in a gas-solid spouted bed of 0.152 m inside diameter by the means of advanced gas-solid optical ibre probe technique. The factorial design of the experiments method was applied on the experimental results to evaluate the effect of these variables on the spout diameter.2 1605 Viscosity-Concentration Relationships for Nanodispersions Based on Glass Transition Point Rajinder Pal Using free volume arguments, a simple model is developed for the zero-shear relative viscosity of nanodispersions taking into consideration the solvation and aggregation of nanoparticles. The zero-shear relative viscosity data of 16 sets of nanodispersions are found to collapse onto a single curve when the data are plotted as relative viscosity versus volume fraction of solvated nanoparticles. The zero-shear viscosity of nanodispersions diverges at the glass transition volume fraction of solvated nanoparticles of about 0.58. Above the glass transition concentration of solvated nanoparticles, the correlation of relative viscosity of nanodispersions is not successful.3 References 1 S. Rahmani, M. Mohseni, Can. J. Chem.
