Formaldehyde Concentration

Tungsten carbide (WC) nanostructures were prepared by carbothermal reduction (CR) of tungsten-impregnated pinewood-derived activated carbon (AC) at 1000 °C under an inert atmosphere. Brunauer-Emmet-Teller (BET) surface area, pore structures of the AC, and catalyst samples were evaluated by N2 adsorption-desorption experiments. The structures of the catalysts were characterized using X-ray powder diffraction (XRD). The morphologies and particle structures of the synthesized WC nanoparticles were investigated by field emission scanning electron microscopy (FESEM) and high-resolution transmission electron microscopy (HRTEM). The WC/AC material was used as support of the platinum catalysts for catalytic oxidation of formaldehyde (HCHO) from interior sources. Pt-WC/AC catalysts with different platinum loadings were assessed for the catalytic oxidation of HCHO at low temperature. The catalytic performance was found to be significantly influenced by reaction temperature, initial formaldehyde concentration, relative humidity, and space velocity. The testing results demonstrated that HCHO can be totally oxidized by the 1 wt% Pt-WC/AC catalyst in the gas hourly space velocity (GHSV) = 50,000 h−1 at 30 °C with a relative humidity (RH) of 40%.

Adsorption Rates

The adsorption of cefradine was carried out using biological adsorbents of powder and carbon prepared from orange peels, an agriculture by-product. The equilibrium was easily reached in less than 10 minutes, with adsorption rates of more than 98%. Cefradine showed a firm combination to the adsorbent, which could hardly be damaged or affected by pH values. After equilibrium was reached within 1 h, no desorption behavior was observed in the next 30 minutes. The adsorption process could be well fitted thermodynamically to both Freundlich and Langmuir equations. Similar results could also be obtained using ashes of orange peel, as well as carbon prepared from pistachio and peanut hull, indicating an attractive option to treat industrial wastewater.
