【Abstract】 The mechanisms and rules of adsorption of one kind of Nacylsarcosine at Fe3O4 nanoparticle surface were investigated.The adsorption models under different conditions of pH and the quantity of Nacylsarcosine were established according to the principle of adsorption of surfactant at the interface of solid/liquid,the hydrophobic/hydrophilic property of nanoparticle,and IR spectra of the coated particles.更多还原
