Biosorption of the lead ions from aqueous solutions using dum palm kernel was studied, the lead ion removal depends on the contact time, pH and adsorbent dosage. The optimum contact time, pH and adsorbent mass with in the experimental limit of this work were 100 minutes, 6-7, and 2.5g/L respectively. The maximum percentage of lead ions removed was 87%. The data fitted well with Temkin and Langmuir models, the regression correlation were obtained to be 0.9660 and 0.8667, respectively. The biosorbent may be economical if developed further for industrial wastewater and natural contaminated water treatment.

Bagasse pith was tested for its ability to remove cadmium and lead ions from aqueous solutions under two modes of operation, i.e. in batch systems and continuous flow systems. Time dependency experiments showed a very rapid adsorption of these cations by bagasse pith. Thus, 62% of cadmium ions and 84% of lead ions were taken up by the bagasse pith at pH 6 and ca. 99% of each cation was recovered by treatment of the pith with 0.1 M HCl. The breakthrough capacity, Q0.5, the number of theoretical plates and the theoretical plate height were calculated. The capacity of bagasse pith was found to be 6.2 and 8.5 mequiv./g for cadmium and lead ions, respectively. The feasibility of using bagasse pith for cadmium and lead ion removal from wastewater streams was addressed.

A new Gelatin-glutaradehyde-Poly(vinyl alcohol) bioadsorbent was synthesized by immobilizing Poly(vinyl alcohol) onto gelatin followed by cross-linking. This technique gives the bioadsorbent of gelatin good chemical resistance and mechanical strength. SEM and FT-IR were conducted for characterization of the bioadsrobent. A comprehensive adsorption study of Copper(II) removal from synthetic aqueous solution by adsorption on this bioadsorbent was conducted regarding the effects of initial pH, time, and copper(II) initial concentration. The adsorption data were applied to Freundlich isotherm equation and its contents were calculated. The results obtained showed that the new absorbent has good performance for the removal of copper(II).
