Problems solved by technology

External source treatment is mainly an anion machine based on negative oxygen ion neutralization and sedimentation and Brownian motion. Source treatment is mainly a diesel particulate filter based on multi-stage filtration technology and electrostatic dust removal technology based on electrostatic adsorption. The common limitations of both are that the equipment is too expensive, and its energy consumption is also very large, and the dust removal efficiency is low.

Abstract

The invention provides an ionic polymer and a preparation method and application thereof. Different rare earth ionic liquids are in reaction with polyvinyl pyrrolidone under mild conditions at different molar ratios, and a series of novel functional materials with fine particle adsorption properties are obtained. The materials have not only the characteristics of high thermal stability, high phase state stability and the like of the rare earth ionic liquids but also the characteristics of high fine particle adsorption rate, durable adsorption property, renewability and the like so that the materials can be applied to various fields. More importantly, the preparation technology of the method is simple, the raw materials are easy to obtain, the cost is low, no organic solvent is used, the raw material utilization ratio is high, and the materials are green and environmental-friendly and can be applicable to large scale industrial production.

Description

technical field [0001] The invention belongs to the field of rare earth functional materials and their preparation and application, and relates to an ion polymer and its preparation method and application. Background technique [0002] With the continuous development of the world economy, urban air pollution is becoming more and more serious. Among many air pollutants, PM2.5 is the most harmful. Due to its small particle size and large specific surface area, it can absorb a large amount of toxic and harmful substances, and at the same time, it can be inhaled into the lungs of humans, causing various diseases, even lung cancer. In addition, PM2.5 is also the direct cause of smog. The source of PM2.5 is mainly anthropogenic, so how to control the emission of PM2.5 from the source has become an urgent problem. [0003] The existing PM2.5 removal technologies are mainly divided into out-of-source treatment and source treatment. External source treatment is mainly an anion ma...
