【摘要】：纳米颗粒在工业和化妆品等行业中的大规模应用,致使大量纳米颗粒进入水环境中,不可避免的产生了一系列的环境问题,同时对生物和人体造成不良影响,因此水环境中纳米颗粒的富集及其检测技术受到广泛关注。目前,多种技术可对水环境中痕量纳米颗粒浓度等特征进行检测,但其在灵敏度和精度方面均存在一定局限性。归纳了目前水环境中纳米颗粒的预处理技术,如超滤分离技术、色谱分离技术、固相萃取技术及浊点萃取技术;综述常用的纳米颗粒与离子检测技术,如光谱分析技术、电感耦合等离子质谱技术及电化学技术。通过对各种方法进行对比分析,使纳米颗粒预处理及检测技术能够被系统广泛的认识。并在此基础上对纳米颗粒的预处理及检测技术的发展前景进行了展望。
[Abstract]:The large-scale application of nanoparticles in industries such as industry and cosmetics has led to a large number of nanoparticles entering the water environment, which inevitably produces a series of environmental problems, and at the same time has a negative impact on biological and human beings. Therefore, the enrichment and detection techniques of nanoparticles in water environment have been paid more and more attention. At present, many techniques can be used to detect the concentration of trace nanoparticles in water environment, but there are some limitations in sensitivity and precision. The pretreatment techniques of nanoparticles in water environment, such as ultrafiltration separation, chromatographic separation, solid phase extraction and cloud point extraction, are summarized. Inductively coupled plasma mass spectrometry and electrochemical technology. Through the comparison and analysis of various methods, the pretreatment and detection techniques of nanoparticles can be widely recognized. On the basis of this, the prospect of pretreatment and detection technology of nanoparticles is prospected.
