Patent number: 11684905Abstract: A biochar-derived adsorbent preferably from Sargassum boveanum, macroalgae can be used for removing phenolic compounds, such as 2,4,6-trichlorophenol and 2,4-dimethylphenol, from aqueous solutions. The carbonization can improve the removal capability of the macroalgae adsorbent for such phenolic compounds with removal efficiencies of 60% or more from high salinity seawater and 100% from distilled water. The adsorption may occur through a mixed mechanism dominated by physisorption following pseudo second-order kinetics. The adsorption of the phenolic molecules may be spontaneous, endothermic and thermodynamically favorable.Type: GrantFiled: April 12, 2022Date of Patent: June 27, 2023Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Mazen Khaled Nazal, Nabeel Saeed Abuzaid

Patent number: 11517876Abstract: A method of forming an activated carbon sorbent from a seagrass. The method involves treating a seagrass with a base solution to form an intermediate solid, drying the intermediate solid to form a precursor, and pyrolyzing the precursor at 600 to 1000° C. to form the activated carbon sorbent. Preferably the seagrass is Halodule uninervis. The activated carbon sorbent is used in a method of removing an organic pollutant from a contaminated water. Preferred organic pollutants removed are phenols, specifically 2,4-dimethylphenol and 2,4-dichlorophenol.Type: GrantFiled: May 11, 2022Date of Patent: December 6, 2022Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Mazen Khaled Nazal, Nabeel Saeed Abuzaid
