松香基氨基化聚合物微球的制备及吸附性能
Preparation and adsorption performance of rosin-based amination polymer microspheres
摘要
Abstract
Amino silane coupling agent(KH-792)was used to modify rosin-based hydroxylated polymer microspheres,the effect of reaction temperature,reaction time,and the amount of KH-792 on the performance of the microspheres was studied. The polymer microspheres were characterized by Fourier Transform Infrared Spectroscope(FTIR),Thermogravimetry Analysis(TGA),Scanning Electron Microscope(SEM)and X-ray Photoelectron Spectroscopy(XPS),amino contents of the microspheres were tested by the conductometric titration method. The adsorption of the ethyl violet on the polymeric microspheres with different amino contents was investigated. The results showed that the rosin-based amination polymer microspheres were prepared successfully,which possessed good spherical shapes and monodispersities. The thermal stability of the polymer microspheres was higher than that of the hydroxylated polymer microspheres. The amino content of the microspheres was 181 μmol/g when the amount of KH-792 was 70%,based on the hydroxylated polymer microspheres,after reaction at 90℃ for 10h. For 5min,the maximum adsorption capacity of the microspheres to the ethyl violet was 57.02mg/g at 328K,with the ratio of the solid to liquid at 1 g/L and the pH=9.5.关键词
