Adsorption Mechanism of Congo Red on Mg–Al-layered Double Hydroxide Nanocompound

In this work, congo red (CR) was removed by applying carbonate intercalated Mg-Al-layered double hydroxide (Mg-Al-LDH) nanocompound as an adsorbent. Batch adsorption experiments performed under various temperatures, ionic strengths, initial CR concentrations, alkalinities and shaking rates. The maximum adsorption capacities of Mg-Al-LDH for CR were 100, 105 and 86.8 mg g -1 at 308, 318 and 328 K, respectively. Adsorption sites of Mg-Al-LDH for...
