Embodiment 1

[0032]Extraction of active substances of Enteromorpha: Cut Enteromorpha fibers into main fiber length <10mm, soak in hot water at 40-60°C to remove sediment. Enteromorpha fibers are placed in an ultrasonic generator with a pH value of 5-6, a solid-liquid ratio of 1:35-40, an ultrasonic power of 1000W, a frequency of 28kHz, and extraction at 40-60°C for 25 minutes. A mixed solution of n-butanol and chloroform (n-butanol: chloroform = 1:4-5) was mixed with Enteromorpha extract and shaken thoroughly for 30 min. Using centrifuge to centrifuge, the final extract includes sugar alcohol, fatty acid and crude fiber.

[0033] Gel material formula: Enteromorpha extract 60%, expanded graphite 15%, iron nitrate 4%, cobalt nitrate 8%, citric acid 8%, ammonia water 4%.

[0034] Sol-gel treatment process: Ferric nitrate, cobalt nitrate and citric acid are completely dissolved in the reaction kettle at a ratio of 1:2:2, and ammonia water is added to keep the pH of the solution between 7.0 an...

Abstract

The invention relates to an enteromorpha gel oil suction material and a preparation method thereof, the gel oil suction material comprises the following components: 60-70% of enteromorpha extract product, 10-15% of expandable graphite, 2-4% of ferric nitrate, 5-8% of cobalt nitrate, 8-12% of citric acid and 2-4% of ammoniacal liquor. According to the invention, enteromorpha with abundant output in sea is taken as a raw material, sugar alcohol, aliphatic acid and crude fiber extracted in enteromorpha are taken as base, and are mixed with expandable graphite by using a sol-gel method, the gel oil suction material can be recovered and used with high efficiency and environmental protection, the molecular structure of three-dimensional fiber mesh can greatly absorb oil molecule. The oil suction material has good oil adsorption performance, oil suction can reach saturation in 60-80 minutes under dynamic state, the saturation adsorption multiple is 40-60 which is higher than that of the current resin oil suction material and biomass oil suction material, and the enteromorpha gel oil suction material has the advantages of fast oil suction speed, good oil binding capacity and low cost.

Description

technical field [0001] The invention relates to the technical field of oil-absorbing materials, in particular to an enteromorpha gel oil-absorbing material and a preparation method thereof. Background technique [0002] Petroleum and its products enter the ocean or other water bodies due to accidents such as blowouts, leakage of transport ships, collisions, shipwrecks, and oil pipeline leakage during the process of mining, refining, transportation, and use, resulting in increasingly serious marine oil pollution. Oil-absorbing materials can effectively deal with marine oil spills, and have the characteristics of high efficiency, economy, and easy oil recovery, but there are also many shortcomings. [0003] Organic synthetic oil-absorbing resin materials are mainly polymeric materials, such as polypropylene and polyurethane foam. Due to their oleophilic and hydrophobic properties, it has better adsorption properties than other types of materials and can be reused. However, t...
