Abstract:The experiments of formaldehyde (HCHO) removal from technology and photooxidation-adsorption technology were
air were performed with photooxidation technology, adsorption introduced respectively.
technology, and photooxidation-adsorption technology respectively.
According to results of experiments, the photooxidation-adsorption 2 Experiment
technology had the best removal efficiency of HCHO than two others,
and the relative air humidity played an important role to these Materials and experimental apparatus
technologies. After the photooxidation-adsorption treatment, the Ultra-fine activated carbon fiber (UFACF) was taken as
