Abstract: Formaldehyde,phenol and trichloroacetaldehyde are three main volatile organic pollutants in water,which cause great harm to the environment.Mesoporous silicon modified PES nanofiltration membrane was prepared by phase inversion method.The effects of reaction time and pH on the degradation of formaldehyde,phenol and Trichloroacetaldehyde in water by the membrane were investigated.The results showed that the best reaction time 10 minutes,and pH value of solution was 11.The degradation rates of formaldehyde,phenol and Trichloroacetaldehyde were 55.5%,42.5% and 67.7% respectively.It provided a feasible way for the removal of formaldehyde,phenol and three chloral aldehyde in water.
