Embodiment 1

[0059] Preparation method and application of polymer-based nanocarbon material, in fact, the form of application is:

[0060] 1) 5 g of seven water chloride is dissolved in 50 ml of ethanol and 100 ml of ultra-pure water, 10 g of chloromethylstyrene-divinylphenylene copolymer, stirred at 50 ° C for 12 h;

[0061] 2) Place the product from which step 1) is placed at 60 ° C to a solid-liquid ratio of 1000 g / L to obtain product B;

[0062] 3) Turn into the product B obtained from step 2) at 60 ° C to the compression Co 2 , CO 2 The pass rate of 50 ml / min was 30 mL / min, and the mixture was stirred at room temperature for 8 h at 60 ° C for 8 h, resulting in product C;

[0063] 4) Use 10% NaHCO at normal temperature. 3 The solution was washed with 1BV / H flow rate to wash solidification for 2 h, resulting in product D;

[0064] 5) The product D was added to 400 ml of 5% NaCl solution, stirred at room temperature until the pH of the NaCl solution supernatant was in the range of 6....

Embodiment 2

[0074] The present embodiment is a method and application of a polymer-based nanocarbon material, which is basically forth in Example 1, but also adjusts some of the parameters, still achieving the same effect. details as follows:

[0075] Concentrate in step 2) to a solid-liquid ratio of 500 g / L;

[0076] In step 3), in 50 ° C product B is introduced into CO 2 The flow rate was 20 ml / min, and the mixture was stirred at room temperature for 12 h then stirred at 50 ° C for 8 h;

[0077] Step 4) 3% NaHCO 3 The solution was lubricated in 1BV / H flow rate for 2 h;

[0078] Step 6) The resulting product was added to 200 ml of 20% ethanol water for 0.5 h, and the excess liquid was removed from 30 ° C.

[0079] The polymer-based nanocarbon carbonate produced by this example was 10.08%; the degree of crystallinity was 30%; the particle size of nanocratic carbonate was 10 to 50 nm. The p adsorption experiment was performed in accordance with Embodiment 1 to measure the amount of P ads...

Embodiment 3

[0081] The present embodiment is a method and application of a novel polymer-based nanocarbon carbonate material. Basically, in Example 1, it is only adjusted to some parameters, and it can still achieve the same effect. details as follows:

[0082] Step 2) first concentrated at 50 ° C, then warmed to 60 ° C, concentrated to solid-liquid ratio of 700 g / L;

[0083] Step 3) Top Co in product B at 30 ° C 2 The flow rate was 60 mL / min, and stirred at room temperature for 12 h after stirring at 60 ° C for 8 h;

[0084] Step 4) 5% NaHCO 3 The solution was lubricated in 1BV / H flow rate for 2 h;

[0085] Step 6) The resulting product was added to 200 ml of 20% ethanol water to stir 0.5 h, and then dried at 40 ° C after removing excess liquid.

[0086] The polymer-based nanocarbon carbonate produced by this embodiment was 11.8%; the degree of crystallinity was 48%; the particle size of nanocratic carbonate was 10 to 50 nm. The P adsorption experiment was measured by the Method in Exa...

Abstract

The invention discloses a polymer-based nano-lanthanum carbonate material, a preparation method, an application and a regeneration method, and belongs to the field of sewage treatment. A polymer-based nano-lanthanum carbonate material, the polymer-based nano-lanthanum carbonate material is a spherical particle, including a macroporous resin sphere uniformly distributed with nano-lanthanum carbonate particles in the hole; lanthanum in the polymer-based nano-lanthanum carbonate material The element mass fraction is 10.08-14.3%, and the crystallinity is 30-95%. The adsorption amount of phosphorus by the polymer-based nano-lanthanum carbonate material decreases with the increase of crystallinity, and the regeneration performance increases with the increase of crystallinity. The adsorption rate of phosphorus is 24.4~36.5mg / g. The polymer-based nano-lanthanum carbonate material of the present invention can be used to efficiently remove phosphorus of different concentrations in water.

Description

Technical field [0001] The present invention belongs to the field of sewage treatment, and more particularly to a polymer-based nanocarbon material, preparation method, application, and regenerative method. Background technique [0002] Phosphorus is an indispensable life element and is also a natural resource for unsquetting. At present, human beings need a large number of phosphite phosphate to maintain food supply, but the mineral reserves are limited, and it has become increasing. However, the mining phosphorus has entered the implanted object, most of which will be lost during the transfer process, which will lead to severe water body and eutrophication, and deteriorate the water, and even the water, red tide, etc. Aspects can cause serious pollution by radial infiltration. These issues have pose a great threat to the environment and human health. Therefore, from the water body to the phosphorus and recycling is not only the key to solving water pollution, but also the susta...
