Embodiment 1

[0018] Example 1: Taking green surfactant dodecyl betaine (BS-12) modified montmorillonite as an example, an organic montmorillonite adsorbent was prepared.

[0019] At room temperature, weigh 30g of dried and pulverized montmorillonite in a conical flask, add distilled water according to the water-to-soil ratio of 20:1, and stir to form a suspension; then add 30g of green surfactant dodecyl betaine (BS-12), stir to mix. At 60°C, ultrasonic treatment at 40kHz for 10 minutes, take it out, wash with water, filter, dry at 80°C, grind, and pass through a 100-mesh sieve to obtain the organic montmorillonite adsorbent 100% BS-Mt.

Embodiment 2

[0020] Example 2: Taking green surfactant dodecyl sultaine (SB-12) modified montmorillonite as an example, an organic montmorillonite adsorbent was prepared.

[0021] At room temperature, weigh 30 g of dried and pulverized montmorillonite in a conical flask, add distilled water according to the water-to-soil ratio of 20:1, and stir to form a suspension; then add 30 g of green surfactant dodecyl sulfo Betaine (SB-12) stirred and mixed. Ultrasonic treatment at 60°C and 40kHz for 10 minutes, take it out, wash with water, filter, dry at 80°C, grind, and pass through a 100-mesh sieve to obtain the organic montmorillonite adsorbent 100% SB-Mt.

Embodiment 3

[0022] Embodiment 3: Taking organic montmorillonite as an example to fix gasoline, kerosene and heavy oil

[0023] Under normal temperature, get 1g of the organic montmorillonite adsorbent BS-Mt in Example 1 and add in the beaker that 100g gasoline, kerosene and heavy oil are housed respectively, after stirring for 30 minutes, the oil absorption reaches equilibrium, drain with a sieve, and measure its saturation Oil absorption. After testing, the oil absorption of gasoline, kerosene and heavy oil are 7, 20 and 48g / g respectively, which has obvious fixed retention effect.

Abstract

The invention relates to a preparation method of montmorillonite as a novel overflowed oil pollution absorbing material, which comprises the steps of: preparing montmorillonite into a turbid liquid, wherein the mass proportion of water to soil is 10:1-20:1; adding dodecylbetaine (BS-12) or dodecyl sulfobetain (SB-12) as a green surface active agent, stirring for 5-10min to ensure that the green surface active agent is dispersed uniformly; ultrasonically treating for 10-20min; carrying out solid-liquid separation by using a filtering method, washing with water; and drying, crushing and the like. The invention has the advantage that the green surface active agent can generate ion exchange action with positive ions among the montmorillonite to enter among montmorillonite layers to ensure that the dewatering property of the montmorillonite can be enhanced and the swelling performance is improved, thus the oil spilling pollution can be more effectively held back.

Description

technical field [0001] The invention relates to a preparation method of montmorillonite, an adsorption material for oil spill pollution. Background technique [0002] In recent years, with the rapid development of my country's industry, the amount of oil exploration, organic matter production, storage and transportation has increased greatly, resulting in frequent oil spill incidents and organic pollution incidents in my country in recent years, and environmental problems have become increasingly prominent. After various accidents, a large number of Oily substances and toxic and harmful organic substances migrate and spread to the surrounding soil and water bodies, seriously damaging the ecological environment, people's health and social security. For example, in July 2010, the explosion and fire of the Xingang oil pipeline in Dalian City caused crude oil to flow into the nearby sea area, resulting in a seawater oil spill pollution accident, which seriously damaged the land a...
