Rice husk is one of the byproducts of rice production which could be used in bios01ption processes for removal of toxic heavy metals from synthetic wastewaters. fu this study the application of rice husk as a biosorbent was investigated for removal of cadmium ions from aqueous solutions. Several batch experiments were conducted with different values of test conditions including pH, temperature, contact time, sorbent concentration and size, and rotation speed. The results showed different efficiencies for different experimental conditions which confmn. The greatest removal percent was 34.50 and the least was 2.32 with Q value, milligram of metal removed per gram of sorbent, of 2.30 and 0.24, respectively. This suggests the imp01tance of these parameters for the process, a point for future studies in batch or pilot scales
