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.
