The potential of banana peel (BP) on the cesium removal from aqueous solutions is study by using different design parameters by adsorption process. The design parameters studied to adsorb cesium using BP as an adsorbent material were initial concentration of cesium , absorbance material packing height which was BP, pH of cesium feed inlet, treatment time, feed flow rate and feed temperature, results show that the higher removal efficiency was 97.50 % for cesium 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. By this way we can possess different benefits which are: remove the hazard and toxic cesium contaminated the water and get rid of waste BP.

The ability to remove perchlorate anions was investigated by the adsorption technique in a laboratory scale and by a batch type unit from contaminated aqueous solutions prepared at specific concentrations. The adsorption process was carried out using banana peels, which were chosen as an available, cheap, and lowcost adsorption media. The studied operating conditions in the treatment process were the acidic function, shaking speed, contact time, temperature, in addition to the initial concentration of perchlorate, which ranging from 1-10, 100-400 rpm, 10-180 min, 20-50 ºC, 50-1000 ppb respectively, while the dose of adsorbent media ranged between 0.5-6 g and the particle size ranged from 0-Pan. The experimental results showed that the removal efficiency of perchlorate changes directly with the shaking speed, contact time, particle size and the dose of adsorbent, while it was inversely with the remaining variables for certain levels. Thus, two types of contaminants were disposed of simultaneously in a beneficial, and eco-friendly manner, reaching to Zero Residue Level (ZRL).
