The adsorption of malonic acid on the rice (Oryza sativa L.) bran was studied under various conditions such as temperature, contact time, adsorbent dose and concentration of adsorbate. In this case Rice bran is one of the important agricultural wastes which in this study is used from it as adsorbent. The rice bran is a beneficial source of lots of lignin, cellulose and silica with adequate adsorptive capacity that can be uses as a sorbent. In this research Batch adsorption experiments were conducted and the results showed that the adsorption was dependent on all these parameters. The adsorption capacity was found to be 1.24 mg/g. The Sorption of malonic acid on the rice bran was rapid during the first 20 minutes and the equilibrium was found to be attained within 50 mines.
