Experiments prove that the organic microporous polymer provided by the invention can fast adsorb heavy metal materials in the drinking water, so that the heavy metal content is lower than the drinkable limit; the nanometer organic microporous polymer scan be widely applied to drinking water purifications.

Description

technical field [0001] The invention belongs to the field of organic microporous polymers, in particular to a nanometer organic microporous polymer and a method for absorbing heavy metals in drinking water. Background technique [0002] In recent years, organic microporous polymers have received special attention because of their unique properties such as high specific surface area, low skeletal density, and high chemical stability, and are widely used in adsorption and separation, heterogeneous catalysis, gas storage, optoelectronics, and semiconductors. and other fields. The Davankov resin obtained by hypercrosslinking styrene polymers through the Friedel-Crafts reaction is one of the earliest organic microporous polymers. The research on this polymer has been very in-depth, and industrial production has been realized in the 1990s. However, it is difficult to deal with the toxic and highly corrosive by-product hydrogen halide released during the production process. Hyper...

Problems solved by technology

However, the synthesis of conjugated microporous polymers, porous aromatic compounds and other organic microporous polymers often requires the use of transition metal catalysts or noble metal catalysts. Large-scale production of porous polymers

At the same time, the synthesis of these monomers is also relatively complicated. The synthetic monomers generally contain ethynyl groups or spiro ring structures that control the three-dimensional structure, and halogen-containing by-products are also produced during the synthesis process.

Therefore, large-scale production of organic microporous polymers remains challenging
