Synthesis of non-ionic hydrogels for non-ionic pollutant removal

Abstract

A method of making a lignocellulose incorporating methacrylate functionality from date palm biomass can include extracting sieved date palm biomass at a first predetermined temperature (110° C.) to obtain an extracted date palm biomass; adding an acid to the extracted date palm biomass to obtain a mixture and stirring and refluxing the mixture at a second predetermined temperature (100° C.) to obtain a refluxed cellulose-hemicellulose-lignin residue; dissolving the refluxed cellulose-hemicellulose-lignin residue in a solvent to obtain a solution; adding triethylamine and methacrylic anhydride to the solution to obtain a reaction solution mixture and stirring while heating the reaction solution mixture to react the triethylamine and the methacrylic anhydride with the solution to obtain a reacted solution mixture; pouring the reacted solution mixture into an ice-cold solvent to obtain a solution mixture and separating cellulose-hemicellulose-lignin residue from the solution mixture via centrifuging; dissolving centrifuged cellulose-lignin residue in water to obtain the lignocellulose incorporating methacrylate functionality.
