Four agricultural wastes: 1) castor bean leaves (CBL), 2) castor bean capsules (CBC), 3) jojoba leaves (JL), and 4) jojoba capsules (JC), were used as adsorbents for the adsorption of Strontium (Sr) from Abu Zaabal industrial wastewater. Three different dosages (0, 0.5, and 1g /100ml wastewater) were used for each at different contact times (1h., 2h., 3h, and 24h). The data showed that: 1) the concentration of Sr in Abu Zaabal industrial wastewater was high (9.8 mg/L), 2) the concentration of Sr has declined overtime and with the use of high dosage of bio-sorbents, 3) the maximum Sr (II) adsorption percentage was observed by using jojoba capsules wastes at 1% dosage and at 24 hours contact time (48.1%).While the lowest percentages were recorded by using castor leaves at 0.5% for 1 and 3 hours of contact time (1.6 and 1.2%). The data also showed that jojoba leaves at concentration 1% recorded the highest adsorption percentage (78%) for Cd. Castor bean and jojoba wastes were found to be attractive low cost materials for the treatment of industrial wastewater to remove Sr and Cd.
