“…However, the understanding of these complex systems has not yet been well established, and consequently, their characterization is very important, helping us to understand better their structure, and to model them for practical applications. While numerous studies have been carried out on the thermodynamic properties of aqueous lactose solutions (e.g., [5,6]), few have taken into account the transport behaviour of these systems (e.g., [7][8][9]). We have been particularly interested in data on these properties for chemical systems, particularly on the diffusion of the systems containing lactose and cadmium ion as cadmium chloride.…”
