Embodiment 1

[0023] The first step, the preparation of raw materials:

[0024] Sodium molybdate by mass ratio: sodium sulfide: sepiolite mineral nanofiber=1: 1: 0.5 takes by weighing required amount of raw material sodium molybdate, sodium sulfide and sepiolite mineral nanofiber, thus completes the preparation of raw material ;

[0025] The second step, the preparation of the mixture:

[0026] The sepiolite mineral nanofibers weighed in the first step are added into deionized water in a mass ratio of sepiolite mineral nanofibers: deionized water=1:10, ultrasonically dispersed for 40min, and then the above first step Add the sodium molybdate and sodium sulfide that have been weighed, and stir magnetically at room temperature for 10 minutes. After the mixed solution is uniformly dispersed, add absolute ethanol according to the mass ratio of sepiolite mineral nanofiber: dehydrated alcohol = 1: 0.1, and continue to stir 10min, adjust the pH to 1 with concentrated hydrochloric acid, thus comp...

Embodiment 2

[0032] The first step, the preparation of raw materials:

[0033]Sodium molybdate by mass ratio: sodium sulfide: sepiolite mineral nanofiber=1: 25: 10 takes by weighing required raw material sodium molybdate, sodium sulfide and sepiolite mineral nanofiber, thus completes the preparation of raw material ;

[0034] The second step, the preparation of the mixture:

[0035] The sepiolite mineral nanofibers weighed in the first step are added to deionized water in a mass ratio of sepiolite mineral nanofibers: deionized water=1:250, ultrasonically dispersed for 50min, and then the above first step Add the sodium molybdate and sodium sulfide that have been weighed, and stir magnetically at room temperature for 20 minutes. After the mixed solution is evenly dispersed, add absolute ethanol according to the mass ratio of sepiolite mineral nanofiber: absolute ethanol = 1: 0.5, and continue stirring 10min, adjust the pH to 1.5 with concentrated hydrochloric acid, thus completing the pre...

Embodiment 3

[0041] The first step, the preparation of raw materials:

[0042] Sodium molybdate by mass ratio: sodium sulfide: sepiolite mineral nanofiber=1: 50:20 takes by weighing required amount of raw material sodium molybdate, sodium sulfide and sepiolite mineral nanofiber, thus completes the preparation of raw material ;

[0043] The second step, the preparation of the mixture:

[0044] The sepiolite mineral nanofiber weighed in the first step is added to deionized water in a mass ratio of sepiolite mineral nanofiber: deionized water=1:500, ultrasonically dispersed for 60min, and then the above first step Add the sodium molybdate and sodium sulfide that have been weighed, and stir magnetically at room temperature for 30 minutes. After the mixed solution is evenly dispersed, add absolute ethanol according to the mass ratio of sepiolite mineral nanofiber: absolute ethanol = 1: 1, and continue stirring 10min, adjust the pH to 2 with concentrated hydrochloric acid, thus completing the ...

Abstract

The invention discloses a preparing method of a composite adsorbent material of molybdenum disulfide and sepiolite mineral nanometer fiber, and relates to solid adsorbents. The sepiolite mineral nanometer fiber, a molybdenum source and a sulphur source serve as the main raw materials, and through preparation of mixed liquor, suction filtration, washing, drying and roasting, the product of the composite adsorbent material of molybdenum disulfide and sepiolite mineral nanometer fiber is prepared. The defects in the prior art that an existing adsorbent material has poor performance of adsorbing organic dyestuff in dye wastewater, and is high in price, high in reproduction cost, and complicated in preparing technology, and cannot be prepared in batch for industrial production are overcome.

Description

technical field [0001] The technical scheme of the invention relates to a solid adsorbent, specifically a preparation method for a composite adsorbent material of molybdenum disulfide and sepiolite mineral nanofibers. Background technique [0002] In recent years, the rapid development of the dye industry has brought high pollution while driving the economy. According to statistics, about 10% to 20% of dyes will be discharged into wastewater during the production and treatment of dyes. Dyes generally have a stable structure and toxicity, and are difficult to biodegrade, which not only causes serious pollution to the environment, but also has carcinogenic effects on humans and other animals. Therefore, the treatment of dye wastewater is particularly important. At present, the widely used method of treating industrial dye wastewater is the adsorption method. The commonly used adsorption material is activated carbon. Wide application of activated carbon. Therefore, it is of ...
