Preparation of polyaniline/carbon nanotube membranes for water treatment
A polyaniline/carbon nanotube membrane with photothermal conversion function and PDS activation ability was designed,and its PDS activation efficiency for water treatment could be largely improved by its unique photothermal conversion ability.The physicochemical properties of membrane were tested by scanning electron microscopy,Fourier transform infrared spectroscopy,X ray diffraction and Raman spectroscopy.As the target pollutant,the phenol was chosen to evaluate the performance of catalytic membrane.The membrane permeability and pollutant removal were obviously improved under the light irradiation(λ＞400 nm).The phenol could be removed 88.5％by catalytic membrane at a high flux of 6 834.2 L/(m2·h MPa),which was 3.1 and 22.7 times higher than that of catalytic membrane without light irradiation and the membrane filtration alone,respectively.The membrane performance could be enhanced with the increase of polyaniline content and hydraulic retention time.
