Embodiment 1-3

[0119] Below is the detailed embodiment 1-3 of the method for utilizing above-mentioned equipment to prepare heavy metal ion adsorbent, and adsorption experiment is as follows:

Embodiment 1

[0121] S1. Weigh 100g of deionized water and add it to the first reaction kettle, then weigh 10g of fullerene, 20g of carboxymethyl cellulose, and 2g of β-cyclodextrin in turn, add it to 100g of deionized water, and stir for 1h. get the mixture;

[0122] S2. Add 50 g of 40% sodium hydroxide solution to the mixed solution described in S1 and continue to stir for 20 minutes to obtain a solution;

[0123] S3. Add 11 mL of epichlorohydrin dropwise into the solution described in S2, and continue stirring for 8 hours to obtain a reaction product;

[0124] S4. The reaction product was filtered and dried, then soaked in ethanol solution with a concentration of 15 g / L pyromellitic acid for 10 min, filtered, and freeze-dried at -20° C. for 24 h to obtain a heavy metal adsorbent.

Embodiment 2

[0126] S1. Weigh 100g of deionized water, add it to the first reaction kettle, then weigh 10g of fullerene, 20g of carboxymethyl cellulose, and 3g of β-cyclodextrin in turn, add it to 100g of deionized water, and stir for 1.2h , to get a mixture;

[0127] S2. Add 55 g of sodium hydroxide solution (40%) to the mixed solution described in S1, and continue stirring for 25 min to obtain a solution;

Abstract

The invention provides a method and equipment for preparing heavy metal ion adsorbent by using fullerene. The equipment includes a control module, the control module is electrically connected with a weighing module, the control module controls the weighing module to weigh raw materials, and the weighing module receives instructions of the control module and weighs the raw materials. The method includes the steps that S1, the fullerene, carboxymethylcellulose and beta-cyclodextrin are weighed by using the equipment, successively added into deionized water and stirred, and mixed liquor is obtained; S2, sodium hydroxide is added into a mixture of S1 and continued to stir; S3, epichlorohydrin is dropped in a mixture of S2 and continued to stir, and a reaction product is obtained; and S4, the reaction product is processed to obtain the heavy metal adsorbent. The method is simple, the equipment facilitates accurate control of the reaction, the adsorbent prepared by the equipment and the method has the good adsorption effect on heavy metal ions of lead and cadmium in the water quality, and the reactivity is high.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a method and equipment for preparing heavy metal ion adsorbents using fullerenes. Background technique [0002] Due to the rapid development of industry, environmental pollution is becoming more and more serious, especially the pollution of heavy metals in water quality. Heavy metals are extremely harmful to the human body. They are easy to accumulate in the human body and are not easy to be discharged. They affect people's intelligence and growth and development, and cause children's growth and development retardation. Therefore, the removal of heavy metal ions in water is an urgent problem that people need to solve. [0003] At present, there are many methods for treating heavy metal ions in water, such as adsorption, chemical precipitation and electrodeposition. However, the adsorption method is currently a relatively environmentally friendly method with good results, so ...
