Abstract

Abstract

The leakage of crude oil from oil tankers, drilling platforms, and oil wells causes oil pollutants to enter the sea and results in the deterioration of the marine ecological environment. In this paper, magnetic hydrophobic Ulva prolifera oil absorption materials were prepared by chemical modification method. The morphology, chemical composition, and wettability of Ulva prolifera at different modification stages were characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and contact angle measurement. After modification with dopamine and dodecanethiol, the contact angle of water and oil of Ulva prolifera was about 131.4° and 0°, respectively, showing excellent hydrophobic and lipophilic properties. The maximum adsorption capacity of the modified Ulva prolifera for crude oil was 7.4 g/g, showing an excellent oil absorption capacity. Simulated oil-contaminated beach experiments illustrated that the adsorption rate of modified Ulva prolifera to the oil attached on the surface of coarse sand particles reached 78.4%, indicating that the hydrophobic magnetic Ulva prolifera has high value and potential in oil pollution control.
