Adsorption of Low-Concentration Formaldehyde from Air by Silver and Copper Nano-Particles Attached on Bamboo-Based Activated Carbon

W. D. P. Rengga, M. Sudibandriyo, and M. Nasikin
Abstract—Bamboo based activated carbon (AC) was modified by attaching silver (AC-Ag) and copper (AC-Cu) nano-particles to reduce the low-concentration of formaldehyde in air. Batch isotherm tests were performed to determine the adsorption capacity of each activated carbon. At equilibrium concentration of 8 ppm, AC-Cu adsorbed 29% higher amount of formaldehyde as compared to the original AC. The highest loading amount was obtained for AC-Ag, being around 0.425 mg/g AC-Ag. The concentration of formaldehyde removed by the AC-Ag was 1.6 times higher than the virgin AC at the same equilibrium concentration.

Index Terms—Formaldehyde, activated carbon, bamboo, silver nano-particles.
