The adsorption of rhodium (III) ions onto gallic acid formaldehyde resin in a batch adsorber has been studied. Adsorption experiments were carried out by agitating 1 g resin particles with 1000 ml of Rh (III) ion solution of the initial concentrations from 16.54 to 88.80 mg/l (293K, 1M HCl). Using Langmuir isotherm, a single stage batch adsorber was designed for different adsorbent mass/treated effluent volume ratios. An initial rhodium concentration of 100 g/m³ is assumed and the required amount of resin particles to recover metal ion content by 75%-99% at various volumes of effluents. For a single-stage adsorption system, thus the adsorbent demonstrated recovery capacity. For example, 1 m³ of solution is to be treated; the required masses of gallic acid resol resin are 25 kg for 75% rhodium removal. In order to recover 90% of the rhodium (III) at various volumes of solution which having different metal concentrations, the required amount of gallic acid resin was calculated. For example, 1 m³ of solution is to be treated, the required amounts of resin particles to reduce the rhodium content by 90% increased from 75 to 76 kg with increase in the initial rhodium metal concentration from 0.1 to 100 g/m³. Through such a projection, a real single stage adsorption system can be designed.
