Fe-hexacyanoferrate was fixed into Mg/Fe hydrotalcite and its potential use to decontaminate strontium aqueous solutions was investigated. The material was characterized using different techniques and its crystallographic structure was simulated. Cation exchange capacity and material chemical stability were studied; it was found that the sorbent has good stability in different solutions. Removal performance was assessed by following batch uni- and multi-variant procedures. The results show that the material has fairly constant buffer ability with limited contribution of temperature changes. Its buffer effect and higher decontamination factor (Df) values, suggest its utilization in pre-treatment step to neutralize and reduce contamination levels in waste solutions. The removal process is reliable at room temperature for slightly to moderately contaminated solutions (≅100mg/l). Removal reaction is chemisorptions via exchange between Fe-hexacyanoferrate (Fe2+) and Sr ions and the reaction kinetics is controlled by diffusive transport through solid-liquid boundary and sorbent particles. The material could be used for 10 stages before reaching its maximum capacity and can be eluted efficiently twice using 0.05MHCL with a concentration factor of 10.
