Abstrakt: In this study, a novel absorpent (MSAR600°C) with a hydrophobic surface and hierarchical porous structure for the removal of kitchen oil was facilely fabricated from the macroalgae, laver (Porphyra haitanensis) by incorporating high-temperature carbonization and alkyl polyglucosides (APG) and rhamnolipid (RL) surfactants modification. The characterization results showed MSAR600°C possessed a louts-leaf-like papillae microstructure with high contact angle (137.5°), abundant porous structure with high specific surface area (23.4 m²/g), and various oxygen-containing functional groups (-OH, C=O, C-O). Batch adsorption experiments were conducted to investigate the effect of adsorption time, temperature, pH, and absorbent dose on kitchen oil adsorption performance. Then the practical application for the removal of kitchen oil using MSAR600°C was also performed. The results showed that MSAR600°C had a higher removal efficiency for kitchen oil (75.98%), compared with the commercial detergent (72.3%). This study demonstrates an example of fabricating a green tableware detergent for enhanced removal performance of kitchen oil. [ABSTRACT FROM AUTHOR]
