Effect of ZnO nanosizing on its solubility in aqueous media

Original language description

Zinc pollution represents a great environmental risk, particularly with regards to the aquatic environment. In this theoretical contribution, the enhanced solubility of ZnO nanoparticles in pure water is predicted based on a simple thermodynamic model. The study used Zn2+, Zn(OH)+, Zn(OH)2, Zn(OH)3 − and Zn(OH)4 2− as dominant species in aqueous solution and a Gibbs energy minimisation method to calculate equilibrium Zn content in this solution. ZnO was investigated in the form of nanoparticles of various shapes, whose very high surface-to-volume ratio implicates their lower thermodynamic stability compared with bulk material. The interfacial energy of the solid ZnO – dilute aqueous solution interface was assessed by applying the average ZnO surface energy and contact angle of a sessile drop of water on ZnO(000¯1)-O surface. At 298 K, the ratio of 2 nm spherical ZnO particles to the bulk material solubility was about 23.7. The calculated results were compared with experimental data and yielded a good agreement. These results are not only of great importance for nanomaterials research but they also have implications for environmental protection. © The Institution of Engineering and Technology 2018.
