| 摘 要： | 采用硅烷偶联剂KH-570对纳米SiO2进行了表面接枝改性,并探讨了改性材料对阿维菌素的吸附性能。通过X射线衍射(XRD)、扫描电子显微镜(SEM)、傅立叶变换红外光谱(FTIR)等技术对表面改性纳米SiO2的结构和性能进行了分析。结果表明,纳米SiO2粒子经KH-570进行表面改性后,其分散性得以改善,对阿维菌素的包封率比改性前的大幅提高,提高率最高达92.6%。用KH-570改性的纳米SiO2可作为一种较为理想的新型生物农药载体。

| Abstract: | SiO2 nanoparticles were modified by silane coupling agent KH-570 and their effects on the adsorption capacity of abamectin were studied.The structure and physicochemical properties of silane modified SiO2 were characterized by XRD,SEM and FTIR.It was shown that SiO2 nanoparticles were modified by KH-570 successfully and dispersivity of the surface modified SiO2 nanoparticles was improved.As a result,SiO2 nanoparticles modified by KH-570 can be used as an ideal carrier for biological pesticides. |
