In this work, the cadmium adsorption capacity of abundant algae waste was investigated. The experiments in this work used batch mode adsorption. The parameters process studied were pH, adsorbent dosage and contact time. The values of pH studied were in the range of 2 to 7, the values of adsorbent dosage were in the range of 0.1 to 2 g while the contact time were in the range of 5 to 240 minutes . The results obtained showed that cadmium adsorption capacity was favored by increasing pH, dosage adsorbent and contact time. From the results obtained it can be concluded that algae was a promising adsorbent for cadmium sequestration from aqueous solution.
