Rhodium removal from aqueous solutions using different design parameters by adsorption process using banana peel. The design parameters studied to adsorb rhodium  using BP as an adsorbent material were initial concentration of rhodium , absorbance material packing height which was BP, pH of rhodium feed inlet, treatment time, feed flow rate and feed temperature, these parameters were varied from (1-100) mg/l, (10-100) cm, (1-8), (1-60) min, (5-100) ml/min and (20-45°C) respectively. Results show that the higher removal efficiency was 96.15 % for rhodium from aquatic solution and this efficiency was decreased with increasing of initial concentration and flow rate while the removal efficiency increased with increasing pH, sorption media bed height and feeding temperature. A mathematical model was proposed for an adsorption packed bed column with porous adsorbent. The mathematical model takes account of both external and internal mass-transfer resistances as well as of nonideal plug flow along the column. Statistical model is achieved to find an expression combined all operating parameters with the removal efficiency for rhodium used in this paper in a general equation. The samples of BP remaining after using it in the removal of rhodium above from aqueous solutions aforementioned were predestined to investigate the utilization of it in useful method. One of these methods was using it as a promoter in preparing type Y-zeolite catalyst, compared these type prepared above with normally type Y-zeolite catalyst and tested in the process of n-heptane catalytic cracking under different operating conditions. The results show that the promoted type Y-zeolite catalyst by rhodium gives higher conversion and better selectivity of n-heptane catalytic cracking than normally type Y-zeolite catalyst.
