A microwave synthesized mesoporous carbon sponge as an efficient adsorbent for Cr(vi) removal.

ABSTRACT: Mesoporous carbon materials have recently attracted immense research interest because of their potential application in water purification fields. Herein, we report the synthesis of a mesoporous carbon sponge (MCS) from a supramolecular microcrystalline cellulose-polymer system triggered by microwave-assisted treatment. Benefiting from the three-dimensional (3D) interconnected mesopores and an evenly distributed ball-like protuberance on the inner surfaces of the macropores, the MCS exhibited a high adsorption capacity (93.96 mg g^-1) for fast Cr(vi) removal within 5 min. Additionally, the MCS can be regenerated and reused after the adsorption-desorption process, and maintained an adsorption capacity of ∼86% after 10 cycles. The high adsorption capacity, significantly reduced tre
