• , the amount of Ag NPs delivered to the cell over time was estimated with a recently developed in vitro sedimentation, diffusion, and dosimetry (ISDD) model [47] and was compared with the result of the ALI exposures. According to the ISDD model, for submerged exposures over 4 h with Ag NP concentrations

• vitro sedimentation, diffusion and dosimetry model (ISDD) according to Hinderliter et al. was used [47] to estimate the effective Ag NP dose delivered to the cells. This model estimates the NP dose delivered to cells as a function of time, by using parameters such as the size, density and aggregation

Because of this, purification and detoxification of industrial waste water has been one of the major challenges. Several methods such as adsorption, filtration, sedimentation and photocatalysis are used for the removal of
