Embodiment 1

[0031] The present embodiment provides a kind of preparation method of MOF composite material, comprises the following steps:

[0032] 1.1 Preparation method of MOF-199

[0033] a) 31.8g of Cu(NO 3 ) 2 ·3H 2 O and 13.8 g of trimesic acid (benzene 1,3,5 tricarboxylic acid) were dissolved in 200 mL of ethanol and placed in a 500 mL Erlenmeyer flask.

[0034] b) The solution was then heated to reflux, continuously stirred for 20 h, and then filtered to separate the blue precipitate, which was washed three times with ethanol.

[0035] c) drying under vacuum conditions at 120°C for 24 hours to obtain MOF-199.

[0036] 1.2 Preparation method of zeolite foam

[0037] a) Add 10 mL of 1.0 mol / L tetrapropylammonium hydroxide solution and 17 g of tetraethyl orthosilicate to 50 mL of deionized water.

[0038] b) Then, 3.2 mL of 1.0 mol / L sodium aluminate was added dropwise to the above solution, and stirred at room temperature for 2 h. The resulting translucent gel was transferred ...

Abstract

The invention discloses an MOF composite material adsorbent for removing benzene and a preparation method thereof, and relates to the field of specific adsorbent design, and the MOF composite material adsorbent comprises MOF-199 and ZF type zeolite foam in a mass ratio of 1: 2. The MOF composite material adsorbent prepared by the invention has strong specific adsorption capacity to benzene, is stable in adsorption performance, and still has an efficient adsorption effect after being used for many times; the structure is stable, benzene does not generate irreversible structural transformation, the pore structure is stable, and the plasticity is high.

Description

technical field [0001] The invention relates to the field of specific adsorbent design, in particular to a MOF composite adsorbent for removing benzene and a preparation method thereof. Background technique [0002] Benzene occupies an irreplaceable position in the field of chemical raw materials because it can synthesize a series of benzene derivatives. It is widely used in plastics, rubber, fibers, dyes, paints, adhesives, detergents, insecticides, etc. Because of its wide application, benzene will inevitably appear in the manufacturing and application of many fields, and even in the new home decoration environment, because of various coatings and adhesives. Scientific studies have shown that inhaling higher concentrations of benzene in a short period of time can cause obvious eye and upper respiratory tract irritation symptoms, conjunctival and pharyngeal congestion, dizziness, headache, nausea, vomiting, chest tightness, weakness of limbs, staggering gait, consciousness,...
