Abstract

See full text

Carboxylic functionalized magnetic nanocomposites can include a magnetic compound, such as Fe3O4, that is encapsulated by a plurality of amino organosilane groups. The organosilane groups can include 3-[2-(2-Aminoethylamino)ethylamino] propyl-trimethoxysilane (TAS). At least some of the organosilane groups can have amino and carboxylic acid substituents. The organic pollutants can include malachite green dye. The carboxylic functionalized magnetic nanocomposites can adsorb dye from solution, such as wastewater. The carboxylic functionalized magnetic nanocomposites can be separated from the solution using an external magnetic material.
