Abstract
ALTERNATION in many of the properties of successive members in homologous series of solid long-chain compounds is well known. We are reporting the direct observation of a similar alternation in the maximum adsorptions of mono-1 and di-carboxylic acids from aqueous solutions on two series of coconut shell charcoals of different degrees of activation. Some alternation in the adsorptions of these acids on a single ‘Norite’ charcoal was found indirectly by Linner and Gortner2, who made a Langmuir extrapolation of their isotherms to maximum adsorption.
