紫外辐照法制备羧基化PP非织造布及其对壬基酚聚氧乙烯醚的吸附
Carboxylated polypropylene nonwoven prepared by UV radiation and its adsorption for nonylphenol ethoxylates
摘要
Abstract
In order to remove the nonylphenol ethoxylates(NPE-10) in water, the carboxylated PP nonwoven (PP-g-AA) was prepared by grafting acrylic acid (AA) onto polypropylene nonwoven through UV radiation. The surface mor-phology and structure of PP-g-AA were characterized by Fourier transform infrared spectrometer, scanning elec-tron microscopy and the contact angle meter. The effects of pH, temperature and the grafting rate of PP-g-AA on the adsorption of nonylphenol ethoxylates (NPE-10) were studied. The results showed that when the solution was neutral or acidic, PP-g-AA has better adsorption effect on NPE-10. When the grafting rate of PP-g-AA was 80％, the adsorption capacity of PP-g-AA on NPE-10 was 138.7 mg/g in the neutral conditions, which was about 6 times that of the original PP. When the temperature was beyond 45℃, the adsorption capacity of PP-g-AA on NPE-10 reduced. The adsorption of PP-g-AA on NPE-10 conformed the pseudo first order kinetic model.关键词
