- Abstract
With the development of nanoscience and nanotechnology industry, nanomaterials have gone into the natural water and it may have some impact ecosystems. This article intends to use nano-silica and zinc oxide different sizes with different concentrations of dispersed in filtered seawater to study the effect of these two nanomaterials agglomeration and sedimentation performance in seawater, to assess nanomaterials in the ocean environmental behavior reference. The results showed that these two nanomaterials, the same particle size, the higher the concentration, the greater the aggregate average particle size; the same concentration, the larger the particle size, the greater the average particle diameter of aggregates. With the particle size, the same concentration of nano-ZnO agglomeration is stronger than in seawater Nano SiO2. At 25 ~ 45 , salinity of seawater 28.3, the concentration of sedimentation rate 50mg / L nano-SiO2 and nano-ZnO increases with increasing temperature. At 25 , salinity of seawater 15.0 to 28.3, the nano-SiO2 and nano-ZnO sedimentation rate solution with salinity increases. Under the same conditions, the nano-ZnO sedimentation rate in seawater nano SiO2.
