| Abstract: | Using polyvinyl alcohol(PVA) as the basic material,the carboxyl carbon nanotubes(c-CNT) as additive,a novel PVA/c-CNT composed ultrafiltration membrane was fabricated by the immersion precipitating phase inversion process.The effects of c-CNT content on the performances of membranes were investigated,such as mechanical property,water flux,the removal efficiency and anti-fouling characteristics.The results showed that the tensile properties,water flux and removal efficiency achieved optimum when c-CNT content was 2 phr,the ability of membrane anti-fouling was improved.Methyl orange and methyl violet,which were representative of azo dyes and triphenylmethane dyes waste water,were as model compounds in order to investigate the adsorption performance of the composed ultrafiltration membrane to dye waste water.The results showed that the adsorption effect was great.The PVA/c-CNT composed ultrafiltration membrane.It could be used to treat industrial dyes waste water. |
