RESEARCH ADSORPTION LEAD ON RICE HUSK DENATURED WITH DITHIZONE BY STATIC METHOD

Abstract

   In this article, we have investigated the adsorptivity of Pb (II) on rice husk modified by organic reagents (Dithizon) using static methods. Optimum adsorption conditions were studied. Highest adsorption was obtained at pH from 6 - 8. The influence of other factors such as contact time, Pb (II) ion concentration, the amount of material ... has studied. The results suggested that the adsorption of Pb (II) from aqueous solution onto the material was monolayer adsorption. The maximum adsorption capacities of Pb (II) on rice husk material are 53.64 mg/g. This research supports possible use this material to separate and preconcentration trace amounts of Pb (II) in some real samples.Keywords: husks, lead, stationary phase, adsorption
