Embodiment 1

[0014] Get 28.3g ferric nitrate and dissolve in 245ml deionized water to prepare a solution, set aside. Weigh La 2 o 3 16.3g in a beaker, then slowly add 29.08ml of nitric acid, after the stirring reaction is complete, pour it into a 100ml volumetric flask, and set the volume to get La(NO 3 ) 3 solution, set aside. Measure 70ml of La (NO 3 ) 3 Add the solution into the prepared ferric nitrate solution, stir magnetically, react at room temperature, slowly add 29.4g of citric acid, 7ml of ethylenediamine and 33.3g of glucose under stirring, stir for 8 hours, and then ultrasonically disperse the mixture After 20 minutes, add concentrated ammonia water drop by drop, adjust the pH to about 9.3, then dilute to 560ml, transfer to the reaction kettle, and react at 170°C for 14h. Suction filtration, wash the filter cake with deionized water and absolute ethanol, dry the filter cake at 100°C, and grind to obtain LaFeO 3 Precursor. Then calcined at 800°C for 2h to obtain LaFeO ...

Embodiment 2

[0018] LaFeO 3 The preparation is with embodiment 1;

[0019] Dissolve 3.32g of KI in 150ml of deionized water, stir magnetically, and slowly add 9.7gBi (NO 3 ) 3 ·5H 2 O and 0.0970g LaFeO 3 ;

[0020] The pH of the above mixture was adjusted to 10 with ammonia water, stirred vigorously at room temperature for 12 hours, filtered with suction, washed with deionized water until neutral, and dried at 60° C. for 6 hours to obtain a composite product.

Embodiment 3

[0022] LaFeO 3 The preparation is with embodiment 1;

[0023] Dissolve 1.7 g of KI in 75 ml of deionized water, stir magnetically, and slowly add 4.9 g of Bi (NO 3 ) 3 ·5H 2 O and 0.24g LaFeO 3 ;

[0024] The pH of the above mixture was adjusted to 10 with ammonia water, stirred vigorously at room temperature for 12 hours, filtered with suction, washed with deionized water until neutral, and dried at 60° C. for 6 hours to obtain a composite product.

Abstract

The invention discloses a preparation method of a triclocarban adsorbent purifying agent. The preparation method comprises the following steps: taking iron nitrate, La2O3, and nitric acid as the main raw materials to prepare LaFeO3; then taking KI and Bi(NO3)3.5H2O as the main raw materials to combine LaFeO3; adjusting the pH by ammonia liquor, fiercely stirring at a room temperature, performing suction filtration, washing the product by water until the product becomes neutral, and drying the product to obtain the triclocarban adsorbent purifying agent. The triclocarban adsorbent purifying agent has the advantages of large adsorption amount and fast adsorption speed, and can be used to process a large amount of wastewater containing triclocarban.

Description

technical field [0001] The invention relates to the preparation of an adsorption material capable of effectively purifying triclocarban pollutants, and belongs to the field of waste water treatment agents. Background technique [0002] The main active ingredients of various drugs and personal care products that are closely related to people's daily life will have many adverse effects on various organisms, especially aquatic organisms in the environment, which has recently attracted people's attention [Lv Xiaoming, China Environmental Monitoring , 2012, 28(4): 118-123]. This series of pollutants are classified as emerging environmental pollutants. Their harm to the environment has received more and more attention, and the research on their governance has far-reaching influence. [0003] As an antibacterial and disinfectant, triclocarban (TCC) has been widely used in pharmaceuticals and personal care products, so the discharge of TCC into the environment is also increasing. ...
