Preparation of MgCl2-coated activated carbon and its adsorption behavior of azo dye from aqueous solution

摘要：

The preparation of MgCl2/AC composite and its adsorption behavior of azo dye from aqueous solution were investigated. The pore size of the new kinds of adsorbent increased with increasing the dosage of MgCl2 solution, while specific surface area decreased. The removal rate of Weak Acid Red 2R from aqueous solution on the MgCl2/AC composite was 93.4 ％ at the optimum conditions of the preparation: activated carbon with 2 M MgCl2 solution at 110℃ for 2 h.
