Application of TRIS-HCL in seawater desalination and composite materials

The full name of TRIS-HCL is tris(hydroxymethyl)aminomethane hydrochloride, which is a multi-application biological buffer comparable to TRIS. However, if your understanding of it is still in pH adjustment, surfactants or organic synthesis intermediates. Then be sure to read this article, I believe it will give you a new understanding of it.

1. TRIS-HCL is used for seawater desalination and concentrated water desalination advanced treatment

The CN111346576A patent discloses a method for preparing a graphene-based hydrogel with a three-dimensional network structure, which contains the component TRIS-HCL. This method mainly solves the problem of low photothermal distillation efficiency of existing photothermal conversion materials, and can be used for photothermal desalination water treatment applications. The preparation method is as follows:

1. Take a Graphene oxide solution with a concentration of 10 mg/mL and disperse it ultrasonically in deionized water for 15 minutes, and prepare a uniform Graphene oxide solution with a mass fraction of 1.5 mg/mL;

2. Add 0.0788g TRIS-HCL to the Graphene oxide solution, stir to dissolve, and keep the solution in weakly acidic;

3. Add dopamine hydrochloride to the above mixture, stir well, and control the mass fraction of dopamine hydrochloride in the solution to 0.5mg/mL;

4. Put the gel solution in a water bath at 95°C for 9 hours of hydrothermal reaction;

5. Take out the Graphene-based hydrogel, wash it with deionized water for at least 3 times, and then soak it in deionized water.

2. TRIS-HCL is used in compound materials TRIS-HCL can also be used in the preparation of inorganic nanoparticle compound materials, mainly used as a buffer solution, with low cost and environmental protection. The preparation method is as follows:

1. Mix silica sol or inorganic nanoparticles, dopamine (DPA), tris(hydroxymethyl)aminomethane hydrochloride (TRIS-HCL) and water evenly, and then stir the resulting mixture to react to obtain polydopamine-modified inorganic aqueous solution of nanoparticles;

2. Dissolve the initiator in water and mix evenly to obtain the initiator solution;

3. Add the monomer and water into the polydopamine-modified inorganic nanoparticle aqueous solution, mix evenly to obtain a reaction solution, and then pass nitrogen into the reaction solution under stirring to remove the oxygen in the reaction solution;

4. Add the initiator solution described in step two into the reaction solution obtained in step three, continue bubbling to remove the oxygen in the mixed solution, carry out soap-free emulsion polymerization reaction under the protection of nitrogen gas, and cool to room temperature after the reaction , to obtain polymer/inorganic nanoparticle composites.
