Abstract In order to obtain environmental treatment materials with formaldehyde purification and antibacterial properties, the urea modified bamboo activated carbon with silver loaded was synthesized by urea impregnation at room temperature combined with glucose in-situ reduction method in this work. The effects of silver loading on the morphology, surface functional groups, pore structure, formaldehyde removal efficiency and antibacterial properties of the composite were investigated. The results showed that the porous structures of bamboo activated carbon were remained, but the specific surface area and total pore volume decreased after loading silver. Compared to raw bamboo activated carbon, when formaldehyde concentration was 220 mg/m³, the removal rate of formaldehyde by the composite increased by 73%. Under dynamic conditions, the effective removal time of formaldehyde was extended by 27 times. The diameters of the inhibition zone to Escherichia coli and Staphylococcus aureus were 5.5 mm and 6.5 mm, respectively, which showed good antibacterial properties. This work provides an effective way to develop a multi-effect high-value-added bamboo activated carbon material.

Key words： bamboo activated carbon silver urea modified formaldehyde antibacterial property
