The release of hydrocarbons (HC) into the marine environment has serious consequences, both economically and ecologically. This work presents an efficient process to remove HC pollution from seawater: cloud point extraction (CPE), considered to be a reliable, inexpensive, and environmentally friendly method, using the readily biodegradable nonionic surfactants Lutensol ON30 and Tergitol 15‐S‐7. A real salt water sample with a high chemical oxygen demand (COD = 1700 mg O2/L) was thus treated. First, the phase diagrams of the binary systems (water–surfactant), and the pseudo‐binary systems (water–surfactant–HC), were determined. Second, after a 24 h settling time, considered as optimal, the extraction results, that is, residual soluble COD, residual percentage of surfactant in the dilute phase and volume fraction of coacervate at equilibrium, were expressed in terms of temperature and initial surfactant concentration. For each parameter, the results obtained were modeled using the response surface methodology and represented on three‐dimensional diagrams. They show that the COD can be reduced to 10 and 15 mg O2/L, using Lutensol ON30 and Tergitol 15‐S‐7, respectively, under seawater temperature conditions. Finally, it was shown that the surfactant can be recycled. The present work demonstrates that CPE can reduce the HC content of seawater on a laboratory scale.

The improper use and overuse of antibiotics have led to significant burdens and detrimental effects on the environment, food supply, and human health. Herein, a magnetic solid‐phase extraction program and an optical immunosensor based on bimetallic Ce/Zr‐UiO 66 for the detection of antibiotics are developed. A magnetic Fe3O4@SiO2@Ce/Zr‐UiO 66 metal‐organic framework (MOF) is prepared to extract and enrich chloramphenicol from fish, wastewater, and urine samples, and a horseradish peroxidase (HRP)‐Ce/Zr‐UiO 66@bovine serum protein‐chloramphenicol probe is used for the sensitive detection of chloramphenicol based on the dual‐effect catalysis of Ce and HRP. In this manner, the application of Ce/Zr‐UiO 66 in integrating sample pretreatment and antibiotic detection is systematically investigated and the associated mechanisms are explored. It is concluded that Ce/Zr‐UiO 66 is a versatile dual‐track material exhibiting high enrichment efficiency (6.37 mg g−1) and high sensitivity (limit of detection of 51.3 pg mL−1) for chloramphenicol detection and serving as a multifunctional MOF for safeguarding public health and hygiene.
