Problems solved by technology

Under normal circumstances, oil spills in these links are very accidental and unpredictable. If an oil spill occurs at sea, due to the influence of sea wind and waves, the pollution will spread further.

Embodiment 1

[0038] Example 1 The adsorbent for removing petroleum pollutants in environmental water samples. The adsorbent is prepared with SBA-15 mesoporous molecular sieves, attapulgite and halloysite nanotubes as carriers, and 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 1g:10mL, and then 0.8mL of aminopropyltrimethoxy was pipetted per gram of carrier material. Silane, pass N 2 Air bubbling deoxygenation 5min; then in N 2 Under the atmosphere, reflux with magnetic stirring at 110°C for 10h, cool to room temperature, filter with suction, wash with toluene, ultrapure water and ethanol in sequence, and remove the resid...

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, it is estimated that 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 Oil in the Sea: Inputs, Fates, and Effects, pp. 1–4), and about 53% are From human oil extraction, transportation and consumption (International Petroleum Industry Environment...
