Embodiment 1

[0038] Example 1 An adsorbent for removing petroleum pollutants in environmental water samples. The adsorbent is prepared with SBA-15 mesoporous molecular sieve, attapulgite and halloysite nanotubes as carriers. Its structural formula is:

[0039]

[0040] where n=10~50.

[0041] The preparation method of this adsorbent comprises the following steps:

[0042] (1) Amino-functionalized SBA-15 mesoporous molecular sieves, attapulgite and halloysite nanotubes were prepared respectively:

[0043] The activated SBA-15, attapulgite, and halloysite nanotubes were used as carrier materials, and dispersed in toluene at a ratio of 1 g: 10 mL, and then 0.8 mL of aminopropyltrimethoxy was pipetted for each gram of carrier material base silane, through N 2 Deoxygenate by air bubbling for 5 min; then in N 2 Under the atmosphere, it was magnetically stirred and refluxed at 110°C for 10 h, cooled to room temperature, filtered with suction, washed with toluene, ultrapure water and et...

Abstract

The invention relates to an adsorbing agent for removing petroleum type pollutants in an environmental water sample. The adsorbing agent is prepared by adopting an SBA-15 mesoporous molecular sieve, attapulgite and halloysite nanotubes as carriers. The structural formula of the adsorbing agent is shown in the specification, wherein n is equal to 10-50. Simultaneously, the invention also discloses a preparation method of the adsorbing agent. The adsorbing agent has the advantages of magnetism, high removing rate, easy separation, capability for recycling petroleum, and the like.

Description

technical field [0001] The invention relates to an adsorbent, in particular to an adsorbent for removing petroleum pollutants in environmental water samples and a preparation method thereof. Background technique [0002] With the rapid development of society, human beings have an increasing demand for energy. As an important raw material for modern industry, oil exploitation has shifted from the early land to the deep sea with rich oil resources. However, the continuously increasing amount of oil extraction is also A series of oil pollution problems have been caused. According to statistics, an estimated 1,300,000 tons of oil enter the sea every year (National Research Council (NRC), 2003. Executive Summary of Oil in the Sea III: Inputs, Fates, and Effects. National Research Council, Committee on Oil in the Sea: Inputs , Fates, and Effects, pp. 1–4), and about 53% came from human oil extraction, transportation and consumption (International Petroleum Industry Environmental ...
