Abstract The aggregation and stability of fullerene (C60) and multi-walled carbon nanotubes (MWNTs) nanoparticle suspensions in aqueous systems were investigated using time-resolved dynamic light scattering, in presence of several electrolytes and natural organic matters. Electrolytes induced carbon nanomaterials aggregation by the mechanism of compressing the double electrode layer, which conformed to the classic colloidal stability theory (Derjaguin-Landau-Verwey-Overbeek, DLVO). In comparison to C60, MWNTs were easier to aggregate and showed weaker stability because of their morphology. In Na+ and Mg2+ solutions, humic acid (HA) could restrain the aggregation of nanoparticles by steric repulsion effect, which was more significant for C60. HA could enhanced the aggregation of nanoparticles by complexing with Ca2+, and this effect was more pronounced on MWNTs. The results of this study elucidated different carbon nanomaterials had various interaction relationship with environmental factors, which would influence their stabilities in water.
