In the present investigation, we focused on the metal ion adsorption ability of Jatropha residue and found it a promising material for adsorbing strontium ions from an aqueous solution. The effects of pH, adsorbent dosage, and agitation time were studied using a batch adsorption technique. Results showed higher adsorption of strontium ions on Jatropha residue in the range of pH 6 to 8. Moreover, the adsorption of strontium ions increased with increasing dosages of Jatropha residue, and the constant adsorption was observed at dosages of 0.07g and higher. Additionally, the adsorption of strontium ions on Jatropha residue occurred rapidly in the early period, and 80% of strontium ions were adsorbed in 3 min of agitation time. Our results showed that Jatropha residue was one effective adsorbent for strontium ions.
