| Abstract: | Manganese ion in solution has been adsorbed in a column packed with oxine-impregnated activated charcoal. In an initial stage, the distribution of Mn ion along the column follows a first order kinetic equation, and the apparent rate constant was determined. With an additional supply of the solution, however, the distribution tends to deviate from the first order kinetic plots. A bed depth/service time relation has been determined experimentally. By introducing a concept of the effective “adsorption capacity” and “adsorption rate constant of the adsorbent, an equation has been presented for estimating the feed application time for breakthrough at any given experimental conditions. With the assumption of a simple first order kinetic adsorption, a bed depth/service time relation was also determined by a numerical calculation, for further examining the characteristics of the relation. |
