- Correlation between Physical Properties of Soluble Organic Compounds in Water and Those Equilibrium Constants in Activated Carbon Adsorption.
抄録
For aromatic compounds, mono- and di- carboxylic acids and monohydric alcohols, the adsorption equilibria from their aqueous solutions onto a granular activated carbon were determined. Then, the equilibrium data were expressed by Freundlich type and the equilibrium constants k and n were obtained. The products k·n and the values of n for those organic compounds were correlated with the molar refraction Rm and the molecular volume Vm, respectively.<br>Then, the relationship between the products and Rm was shown, as follows.<br>log k·n=21.6 Rm+0.953-0.215 Nf (Nf : number of hydrophilic functional group)<br>The products for isomers of butanol could be corrected by use of that for the linear molecule as the standard one and the ratio of those boiling points TB/TB,0, and the effect of adsorption temperature on the products was estimated by comparing with the value at standard temperature T0, as follows.<br>k·n=(k·n)0 (TB/TB,0)4.2 and k·n=(k·n)0 (T0/T)<br>Also, the value of n was correlated with Vm and the effect of adsorption temperature on n was estimated, as follows.<br>log n=0.833 log Vm+3.72 and n=n0 (Vm/Vm,0)0.833 (T0/T)<br>where n0 and Vm,0 indicate n and Vm at standard temperature T0, respectively.
