Embodiment 1

[0024] Embodiment 1 comprises the following steps:

[0025] 1. The peel of grapefruit consists of two parts; one part is the outer skin, the pomelo peel with oil glands, and the other part is the white spongy mesocarp. First, peel off the exocarp with a knife, cut the white spongy mesocarp part of the grapefruit peel into cubes, dry it in an oven at 50-70°C for 12 hours, and grind it into powder. Put 10-15g of the ground powder in 400ml of 1mol / L NaOH solution, heat at 80°C for 3 hours, wash with deionized water until the pH is 7, and freeze-dry after suction filtration;

[0026] 2. Take 10-15g of the above-mentioned dried powder and place it in 400ml of 1mol / L nitric acid solution, heat at 80°C for 2 hours; wash with deionized water until the pH is 7, freeze-dry after suction filtration;

[0027] 3. Put the functionalized pomelo peel in 0.29376g of zinc nitrate and 10ml of methanol solution, ultrasonic for 30 minutes and soak for 12 hours;

[0028] 4. Pour the above solutio...

Abstract

The invention provides a preparation method and an application of a ZIF-8/shaddock peel composite material for CO2 adsorption. The method includes the steps: treating ground shaddock peel (Pp) powderby sodium hydroxide; treating hydrolyzed shaddock peel powder by the aid of strong oxidizing property of nitric acid and freeze-drying the shaddock peel powder; soaking carboxyl functionalized shaddock peel (FPp) powder in solution containing zinc ions; pouring the solution into solution containing methylimidazole, placing the solution into a drying oven for heating, and performing reaction for aperiod of time to obtain an MOF (metal-organic framework) loaded shaddock peel membrane or MOF loaded shaddock peel powder. Raw materials are low in waste utilization cost, wide in source, simple to operate, poisonless, harmless and environmentally friendly and have good adsorbability, and the prepared ZIF-8/shaddock peel composite material for CO2 adsorption is high in CO2 adsorption capacity andremarkable in adsorption speed.

Description

technical field [0001] The present invention relates to a method for CO 2 Preparation and application of adsorbed ZIF-8 / pomelo peel composites. Background technique [0002] With the development of science and technology and the improvement of people's living standards, the resulting environmental pollution is also increasingly concerned by the general public. Among all kinds of pollution, the hazards of greenhouse gases and the severity of their prevention and control are well known. The global greenhouse effect is becoming more and more serious. Greenhouse gases refer to some gases in the atmosphere that can absorb solar radiation reflected by the ground and re-emit radiation, such as water vapor. , carbon dioxide, most refrigerants, etc. Their effect is to warm the Earth's surface, similar to how a greenhouse traps solar radiation and heats the air inside it. The effect of this kind of greenhouse gas on making the earth warmer is called "greenhouse effect". , while th...
