Amenability of carboxylic acids adsorption on surface of activated carbon

The objective of the present study was to investigate the adsorption of benzoic acid (ba),valeric acid (va),propionic acid (pa) and butyric acid (bua) from aqueous solutions at different dosing rate on the surface of activated carbon. different trials were taken in order to determine the interaction between the carbon surface and adsorbent species. the residual concentration of acids was calculated by the titrimetric method. maximum adsorption capacity was found to be 93.37% at dosing rate of 8.75 g for bua and minimum adsorption capacity was measured as 41.47% at dosing rate of 0.69 g for va. keeping the same contact time and mass of activated carbon (2.8 g),the adsorption capacity increases with increasing dosing rate.
