Heavy metal ion such as lead is toxic and represent as hazardous pollutants due to its persistent in the environment. In this study the rice bran was used for the sorption of lead from waste lubricant oil in the presence and absence of ultrasound. The main objective of this study is to get the optimum condition towards lead removal from waste oil in the presence and absence of ultrasound. The effect of temperature, particle size and adsorbent dosage on removal of lead was investigated. Temperatures of solutions and adsorbent dosage were varied from 40 - 90 oC and 1 – 6 g/100 mL, respectively while the particle size of rice bran were prepared in the range of 0 – 200, 400 -500 and 630 - 800 μm.

Of the particle sizes studied, 0 – 200 μm of rice bran exhibited the highest adsorption capacities and in adsorbent dosage studies, the results indicated that the adsorption process reached equilibrium after 4 g/100 mL in presence and absence of ultrasound.
