Adsorption is a separation process of high importance for industry, and is described as ion, atom or fluid molecule transport to the surface of solid material with high specific surface area, and selectively bonding to it. The main reason why this process is so important is due to its selectivity for binding from fluids. That way it is possible to remove unwanted chemical substances from products or to concentrate wanted substances. In this process, adsorbat is the substance that will bond to surface, and adsorbent is solid material on whose surface will it bond. One of the most used adsorbents is active carbon, and that is due to its high surface area and low cost. Activated carbon is suitable for adsorption of nonpolar organic compounds from water due to its nonpolar surface. In this research, the main goal was to observe the impact of flow rate, concentration and height of granulated active carbon (GAC) on adsorption of acetic acid from aqueous solution. Batch adsorption has been done and so provided Freundlich adsorption isotherm. Afterwards, continuous adsorption process was performed in column with active carbon. Results are given as breakthrough curves, or precisely, by graphical dependency of ratio of inflow and outflow concentration and the volume of the outlet solution, and their comparison. Given results show favorable influence of higher concentration, larger amount of active carbon, and bigger flow rate.
