Chemical modification of cobalt ferrite nanoparticles with possible application as asphaltene flocculant agent

open access: yesMaterials Research, 2013
Asphaltenes can cause enormous losses in the oil industry, because they are soluble only in aromatic solvents. Therefore, they must be removed from the petroleum before it is refined, using flocculant agents. Aiming to find new materials that can work as
