Abstract: The adsorption of low concentration of free acid by regenerable chitin was followed by electric conductance measurement. The effect of media such as foreign organic solvent on adsorption was discussed. Experimental results shew that the apparent adsorption constants decreases with decreasing dielectric constant(ε)in an adsorption system.

Key words: regenerable chitin, media, adsorption, free acid
