摘要： |
| 以N,N’-双(3-氨丙基)甲胺为水相单体，均苯三甲酰氯为有机相单体，采用界面聚合的方式制备了荷正电复合纳滤膜。该复合纳滤膜表现出荷正电膜的截留特性，对不同盐溶液的截留顺序为MgCl2>CaCl2>MgSO4>NaCl>Na2SO4。通过扫描电子显微镜、原子力显微镜、衰减全反射红外光谱仪对复合纳滤膜的结构进行表征，利用ZETA电位仪考察该膜表面的荷电性，用接触角测量仪测定膜表面亲水性。同时考察了该款纳滤膜在硬度脱除方面的应用。 |

Composite nanofiltration membrane was prepared through interfacial polymerization using N,N’-bis(3-aminopropyl)methylamine and trimesoyl chloride as monomers. The obtained membrane possesses the characteristics ofpositively charged nanofiltration membrane, whose rejection to inorganic salt decreases in order of MgCl2 >CaCl2>MgSO4>NaCl>Na2SO4. The structures of obtained membrane were characterized using scanning electron microscope, atomic force microscope and attenuated total reflection infrared spectrometer. The surface charge character was evaluated throughZETApotential meter. The surface hydrophilia was estimated using contact angle meter. The hardness removal application of this nanofiltration membrane was also tested. |
