Embodiment 1

[0034] The synthesis of embodiment 1 nanometer organic microporous polymer HOTT-HATN

[0035] 1. Add cyclohexanone octahydrate (529mg, 1.69mmol), 4,5-dichloro-1,2-phenylenediamine (900mg, 5.08mmol) and a magnetic stirring bar into a 25ml double-neck round bottom including a condenser The flask was placed on a magnetic stirrer, then evacuated and filled with nitrogen, and repeated 3 times.

[0036] 2. Transfer 12 mL of glacial acetic acid, which was previously bubbled with nitrogen for 5 min, into the flask through a vacuum tube under nitrogen.

[0037] 3. After reflux at 140° C. for 24 h under nitrogen, the reaction liquid was filtered and washed with 20 mL of hot glacial acetic acid to obtain the first intermediate product in the form of solid.

[0038] 4. Mix the first intermediate product with 15mL 30% nitric acid, then reflux at 140°C for 3h, filter the reaction solution, collect the solid, wash with 10mL deionized water and ethanol, and dry in vacuum to obtain the second...

Abstract

The invention belongs to the field of an organic microporous polymer, and particularly relates to a nanometer organic microporous polymer and a method for adsorbing heavy metal in drinking water. The nanometer organic microporous polymer provided by the invention has a structure shown as a formula (I) shown in description, and comprises a condensed polycyclic aromatic structure unit; the nanometer organic microporous polymer is prepared from triquinoyl octahydrate, 4,5-dichloro-1,2 phenylenediamine and 2,3,6,7,10,11 hexahydroxy triphenylene through reaction; the nanometer organic microporous polymer is fully organic aromatic framework solid capable of being highly recovered; no metal ions are contained; the synthesis does not need a transition metal catalyst; no halogen-containing by-products are generated; green and environment-friendly effects are achieved; a very important function is provided for the green and sustainable development technology. 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...
