Perchlorate Removal Using the Calcination Products of Mg-Al-Fe Hydrotalcite-Like Compounds as Adsorbent

Abstract:

The calcination products of Mg/(Al-Fe) hydrotalcite-like compounds (HMAF) were used as adsorbent to remove perchlorate in affected water. HMAF were synthesized by co-precipitation method at a constant pH value, the best calcined temperature is 500°C and the optimal Mg/Al/Fe molar ratio is 3:0.8:0.2 (CHMAF5%). Factors such as adsorbent dose, initial pH, initial perchlorate concentration affecting perchlorate adsorption were studied. Results showed that the best parameters of adsorbent dose, pH and perchlorate concentration are 0.2g, pH 4-10 and 2000µg/l, respectively. The calcination products of HMAF can be a promising adsorbent for perchlorate removal.
