Embodiment 1

[0017] Example 1 A magnetic thienoyltrifluoroacetone TTA@Fe 3 o 4 Sorbent preparation

[0018] Weigh 1 g of ferric oxide synthesized by coprecipitation method, place it in 100 mL of cetyltrimethylammonium bromide CTMAB solution with a concentration of 10 g / L, and place it at 80 o Heating and stirring in C water bath for 10 h, cooling to room temperature, magnetic separation, and washing the particles with distilled water several times until there is no Br - , 50 o C vacuum-dried for 12 hours, and ground through a 200-mesh sieve; the dried and ground particles were immersed in 100 mL of 1 mg / mL thienoyl trifluoroacetone TTA ethanol solution, at 60 o C stirring for 50min, standing for aging, 50min. Magnetic separation, washed with ethanol and water several times, at 60 o C was vacuum dried for 24h, ground, and sieved to obtain magnetic thienoyltrifluoroacetone TTA@Fe 3 o 4 Adsorbent.

Embodiment 2

[0019] Example 2 A magnetic thienoyltrifluoroacetone TTA@Fe 3 o 4 Sorbent preparation

[0020] Weigh 1 g of ferric oxide synthesized by coprecipitation method, place it in 100 mL of cetyltrimethylammonium bromide CTMAB solution with a concentration of 15 g / L, and place it at 80 o C water bath heating and stirring for 11h, cooling to room temperature, magnetic separation, and washing the particles with distilled water several times until there is no Br - , 50 o C vacuum-dried for 12 hours, and ground through a 200-mesh sieve; soak the dried and ground particles in 100 mL of 2 mg / mL thienoyl trifluoroacetone TTA ethanol solution, and o C stirring for 65min, standing for aging, 65min. Magnetic separation, washed with ethanol and water several times, at 60 o C was vacuum dried for 24h, ground, and sieved to obtain magnetic thienoyltrifluoroacetone TTA@Fe 3 o 4 Adsorbent.

Embodiment 3

[0021] Example 3 A magnetic thienoyltrifluoroacetone TTA@Fe 3 o 4 Sorbent preparation

[0022] Weigh 1 g of ferric oxide synthesized by coprecipitation method, place it in 100 mL of cetyltrimethylammonium bromide CTMAB solution with a concentration of 20 g / L, and place it at 80 o Heating and stirring in C water bath for 12h, cooling to room temperature, magnetic separation, and washing the particles with distilled water several times until no Br - , 50 o C Vacuum-dried for 12 hours, and ground through a 200-mesh sieve; soak the dried and ground particles in 100 mL of 3 mg / mL thienoyl trifluoroacetone TTA ethanol solution, at 60 o C stirring for 80min, standing for aging, 80min. Magnetic separation, washed with ethanol and water several times, at 60 o C was vacuum dried for 24h, ground, and sieved to obtain magnetic thienoyltrifluoroacetone TTA@Fe 3 o 4 Adsorbent.

Abstract

The invention discloses a preparation method and application of magnetic thenoyltrifluoroacetone TTAaFe3O4. A magnetic TTAaFe3O4 adsorbent is synthesized from TTA and magnetic Fe3O4. The synthesized magnetic TTAaFe3O4 adsorbent is applied to adsorption of heavy metal ions Cu2+, the adsorption effect is good, the adsorption amount is large, the desorption conditions are mild, high reproducibility is achieved, and reutilization is achieved.

Description

technical field [0001] The invention belongs to the technical field of water treatment, in particular to a magnetic thienoyltrifluoroacetone TTA@Fe 3 o 4 The preparation method of the adsorbent and the adsorption of heavy metal ion copper ion in water treatment. Background technique [0002] With the rapid development of the economy, a large amount of waste water is discharged, the accumulation of heavy metals in soil and water sources is intensified, and the pollution of heavy metals is also becoming more and more serious. Because heavy metals are easy to bioaccumulate through the food chain, they pose a serious threat to organisms and human health. How to effectively control heavy metal pollution has become a common concern of mankind. Copper ions are a common source of heavy metal pollution in industrial wastewater. Copper is one of the essential trace elements for the human body, which plays an important role in hematopoiesis, cell growth and endocrine gland function...
