Abstract

Particle Size Experiments on the Adsorption of Pb (II) from Polluted Water by Rice Straw. As rice straw is abundantly available in Indonesia and other tropical developing countries as an agricultural waste. This material may be used as a simple and environmentally friendly alternative to remove heavy metals from contaminated water sources for human use. In this paper the effect of particle size of rice straw in adsorbing Pb (II) is studied. The Pb (II) adsorbed by straw is build up in the increasing of Pb concentration in the solution and it reached an optimum at a certain point, which showed that there is a limit in the active sites. At lower initial concentrations of Pb (II) solutions particle size of straw cause much variation in the adsorption of Pb, while surprisingly at increasing initial concentration, bigger particle shows higher adsorption capacity. This study showed that the adsorptive power of rice straw for Pb is independent of particle size.
