Abstract

The removal of lead from a 30 ppm Pb (II) simulated water using Kikuyu as a biosorbents that was prepared by a process of acid hydrolysis followed by a basic hydrolysis was investigated. The adsorption process was conducted in a jar test equipment in order to find out the relationships between the adsorption capacity (Q), the response variable, and the independent variables under study: biosorbents dose, stirring speed and pH. It was found that the maximum capacity of adsorption of 139.35 mg / g was achieved with 0.06 g of biosorbents dose (Kikuyu), 100 rpm for stirring speed and pH 6. The mathematical model that relates Q with the most significant variable, the biosorbents dose (Do) was determined.The kinetics of adsorption follows a first order model (R2 = 0.9445), where the value of k = 0.0089 t-1.The Langmuir model represents the adsorption process ( R2 = 0.9955).
