Abstract

The invention belongs to the technical field of wastewater treatment in environment protection, and discloses a supramolecular hydrogel factor capable of detecting and removing cadmium and a preparation method thereof. The preparation method comprises the steps of preparing the supramolecular hydrogel factor; after compounding the prepared supramolecular hydrogel factor and an inorganic matter according to the mass ratio being (6 to 7): (4 to 3), obtaining the supramolecular hydrogel factor capable of detecting and removing the cadmium; mixing the prepared supramolecular hydrogel factor capable of detecting and removing the cadmium and wastewater to be treated according to the mass ratio of 1:30 to 1:1500, adjusting pH to range from 7.0 to 9.0 through alkali, and after stirring for 20 to 40min, aerating for 1 to 2.5 hours at the normal temperature or under a heating condition. A supramolecular hydrogel formed by the supramolecular hydrogel factor provided by the invention has favorablebiocompatibility; the preparation method of the supramolecular hydrogel factor provided by the invention is short in flow, simple to operate, mild in reaction conditions, high in reaction yield, andsuitable for mass production.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment in environmental protection, and in particular relates to a supramolecular hydrogel factor capable of detecting and removing cadmium and a preparation method thereof. Background technique [0002] Supramolecular hydrogels (Supramolecular hydrogels) refer to nano-aggregates formed by self-assembly of small molecules (molecular weight ≤ 2000, also known as gel factor) with water as the main solvent. This aggregate is a state in which the hydrophilic groups of the gel factor are dissolved in water and its hydrophobic groups are aggregated in water to achieve equilibrium. Different from traditional polymer gels, supramolecular hydrogels are formed through weak non-covalent interactions such as hydrogen bonds, hydrophobic interactions, and π-π stacking. Conditions such as ionic strength, electric field and magnetic field are used to achieve the reversible transition from solution to gel. ...
