A kind of preparation method of double thermosensitive mesoporous imprinted polymer

Abstract

The invention provides a preparation method for double-temperature-sensitive type mesoporous imprinted polymer. The preparation method comprises the following steps: step 1, preparing polymer precursor; step 2, preparing single-temperature-sensitive imprinted polymer; and step 3, preparing the double-temperature-sensitive type imprinted polymer. The preparation method is used for preparing new double-temperature-sensitive type imprinted polymer based on a mesoporous material; the material has excellent temperature sensitive characteristic, has relatively great adsorption capacity on metal ions, and has high selectivity, remarkable separation effect and many reuse times. The preparation method provides a novel method for selectively separating and enriching pollutants in environment.

Description

technical field

[0001] The invention relates to a preparation method and application of a dual-temperature-sensitive mesoporous imprinted polymer, which belongs to the fields of material preparation, separation technology and environmental treatment. Background technique

[0002] Cadmium ions are one of the heavy metal elements that are harmful to the human body. They can be continuously enriched in the human body through the food chain and cannot be degraded in the human body. Even very low levels of cadmium ions are extremely harmful to human health. It is listed as one of the priority monitoring pollutants in water by countries all over the world. Therefore, it is of great significance to selectively and efficiently remove cadmium ions in water. Adsorption is an effective and low-cost method for dealing with heavy metal ions. However, since cadmium usually exists in trace amounts and is affected by other interferences, it is difficult to detect and separate cadmium ions...
