摘要: Abstract Volatile organic compounds, e.g. formaldehyde, could pollute the indoor and outdoor air. Activated carbon (AC) is most widely used adsorbent for removal of this pollutant. In work, an made silver nano-particles attached onto bamboo-based activated (Ag-AC) was prepared. The characterized by FESEM, TEM, SEM-EDX, BET, XRD. FESEM images showed that Ag-AC has less pores than AC, indicating were deposited on pore structures AC. TEM image well distributed carbon. SEM-EDX results confirmed presence Ag-AC, whereas BET specific surface area measurements indicated nanoparticle deposits reduced available adsorption experiments conducted in a continuous fixed-bed column. effect different influent flow rates initial concentrations formaldehyde studied. exhibited much longer breakthrough times during column tests AC at same rate. mass removed 2.36 greater observed experimental data agreed within 5% with predictions Thomas Yoon-Nelson models.
