Abstract

The invention discloses an amino functionalized ionic liquid / hydrotalcite-like compound composite material, and a preparation method and an application thereof. The preparation method comprises: firstly synthesizing an amino functionalized ionic liquid, then taking amino functionalized ionic liquid with different molar masses, employing a coprecipitation method to load the ionic liquid on the surface of the hydrotalcite-like compound, to prepare the amino functionalized ionic liquid / hydrotalcite-like compound composite material with a lamellar structure. The prepared organic-inorganic composite material has the structure and performance advantages of the functionalized ionic liquid and the hydrotalcite-like compound; the composite material, as an absorbent, shows good adsorption removal capability on pollutions such as o-chlorophenol , m-chlorophenol or p-chlorophenol in water, and has substantially better adsorptivity performance than the hydrotalcite-like compound; and the synergy advantage of the amino functionalized ionic liquid and the hydrotalcite-like compound is given a full play.

Description

technical field

[0001] The invention relates to an amino functionalized ionic liquid / hydrotalcite-like composite material; the invention also relates to a preparation method of the composite material and its application in removing pollutants in water bodies. Background technique

[0002] Hydrotalcite-like (abbreviated as LDH) is a kind of two-dimensional nano-anionic clay, and its general formula can be expressed as [M 1-x 2+ m x 3+ (OH) 2 ] x+ (A n- ) x / n mH 2 O, where M 2+ Refers to divalent metal cations, M 3+ Refers to trivalent metal cations, x is M 2+ with M 3+ The molar ratio of A n- It is an anion that can exist stably between layers and has a hydrotalcite layered structure. Because of its advantages of adjustable sheet element composition and charge density, controllable interlayer guest molecules, crystal size, and low biological toxicity, it has been used in organic catalysis, Polymer additives, biomedicine, environmental protection and many other fi...
