Abstract
The continuous increasing usage of nanoparticles (NPs) in industrial and household applications and release of those materials into the aquatic environment may pose risk to different ecosystems affecting its quality. Based on the literature, it is observed that there is lack of availability of direct data relevant to the interactions of NPs in aquatic or soil environment. In this context, a study was envisaged to investigate the transport potential and behavioural aspects of NPs (metal-oxide NPs (Fe2O3, Al2O3) and Mutliwalled Carbon Nanotubes (MWCNTs)) in the presence of inorganic colloids (nanoclay (Montmorillonite-k10)) and organic pollutant (Red-CLB dye) in the aquatic environment. Since it is very intricate to comprehend the kind of interactions between NPs and determine the change in the concentration of NPs during interactions in the aquatic environment, the measured variation in the water quality parameters like hardness, chloride and total dissolved solids (TDS) were used as indicators. The intrinsic properties of NPs like particle size, morphology, functional groups and crystal structure during interactions of NPs were studied using XRD (X-Ray Diffraction), SEM (Scanning Electron Microscope), FTIR (Fourier Transform Infra-Red) and EDX (Energy Dispersive X-ray spectroscopy).The observed types of interactions of NPs in water (adsorption, aggregation, deposition, ion exchange, isomorphic substitution) during the conducted experimental investigations at different pH and ionic concentration might be helpful for further research in this direction. The observed results may be useful for the decision makers on the type of treatment to be given before releasing NPs into the aqueous environment.
