文摘

MCM-41 was synthesized via solgel and modified with citric acid. Adsorbents were synthesized in a short time with environmentally friendly chemicals. Optimal adsorption capacity was achieved with 0.6 M citric acid grafted on MCM-41. Citric acid grafted MCM-41 had a better adsorption than unmodified MCM-41.
