Preparation of Bamboo Activated Carbon and Its Application as Loader of Titanium Dioxide
Activated carbons were produced from bamboo cane through phosphoric acid activation, and their methylene blue and caramel adsorptions were investigated. Activated carbon with high methylene blue and caramel adsorption values was selected to load titanium dioxide with the sol -gel method, and the performance of composite catalyst was discussed according to the removal of formaldehyde in aqueous solution. N2 adsorption results showed that bamboo activated carbon, which was activated under 400 ℃ for 40min with impregnation ratio 3:1 and heating rate 10 ℃/ min, has large surface area and is rich in macro-/meso-pores. The results also showed that the prepared composite photocatalyst could remove formaldehyde distinctly in aqueous solution under the conditions of the catalyst dosage 1.5g, 800mL of 5mg/L aqueous solution of formaldehyde, and exposure in 10w UV-light, and the formaldehyde removal rate was up to 84.28％ in 480min.
