Fe3O4@大黄酸磁性纳米体系对于Pb2 和Mg2 的识别摘 要

当今社会飞速发展,人们的生活品质不断提高,但工业化发展给我们带来好处的同时,也带给我们一系列问题,如严重的污染问题,其中包括废气和污水的随意排放,重金属离子污染成为最棘手的环境问题之一。因此,解决金属离子污染问题成为了首要目标,未经处理的含金属离子的废水废气要禁止随意排放,同时对这类重金属离子我们要寻求快速准确检测的方法,以方便我们更好的处理金属离子污染问题。选择性好、灵敏度高、容易识别、操作简便、快速且成本较低的磁传感器应运而生。磁传感技术现已经应用于生物、化学、物理、环境和生命科学等多个领域,并仍在不断的发挥着它的价值。

Fe3O4@Rehin magnetic nanosystem for the identification of Pb2 and Mg2

ABSTRACT

Nowadays, with the rapid development of society, people#39;s quality of life is constantly improving. However, while the development of industrialization brings us benefits, it also brings us a series of problems, such as serious pollution problems, including the random discharge of waste gas and sewage. Heavy metal ion pollution has become one of the most intractable environmental problems. Therefore, solving the problem of metal ion pollution has become the primary goal. The untreated waste water and gas containing metal ions should be prohibited to be discharged at will. Meanwhile, we should seek rapid and accurate detection methods for such heavy metal ions to facilitate our better treatment of metal ion pollution. Magnetic sensors with good selectivity, high sensitivity, easy identification, simple operation, fast and low cost emerge at the right moment. Magnetic sensing technology has been applied in many fields such as biology, chemistry, physics, environment and life science.

Key words:Ferric oxide、 magnetic sensors、MNPs、 water pollution
