| Abstract: | A composite of TiO2 and bamboo activated carbon was achieved through sol-gel method and its removal of formaldehyde was evaluated.Removal rate of formaldehyde with different pre-adsorbing time,initial concentrations and different catalyst dosages over the composite was investigated.It was shown that the prepared composite photocatalyst remove formaldehyde from aqueous solution distinctly: when the dosage is 1.0g,800mL initial concentration of 5mg/L aqueous solution of formaldehyde,after 1h pre-adsorbing and... |
