Molecular fundamentals of foam fractionation
Foam fractionation of surfactant and protein solutions is a process dedicated to separate surface active molecules from each other due to their differences in surface activities. The process is based on forming bubbles in a certain mixed solution followed by detachment and rising of bubbles through …

Removal of metal ions from solution by foam fractionation methods
Foam separation is used as a method for separation of solute from liquid solutions. The physical chemistry of a foam-liquid system was investigated including studies of foam density, foam stability and foam drainage, and the counter-current flow of liquid and foam. The experimental results obtained …

Foam fractionation and air flotation treatment of a tarsand extraction wastewater
… ascertain the feasibility of using a two-stage foam separation system, with foam fractionation or air flotation as the second stage, to treat a tarsand extraction wastewater; and, 2) to evaluate the effects of four operational variables on the second stage performance. The wastewater was a …

Foam fractionation of biopolymers: studies of protein behaviour in analytical and preparative systems
… of molecular interactions between proteins upon foam quality in batch and continuous operations, and to investigate foam fractionation as a method of protein recovery from real biological feedstocks. Foam stability studies of model protein solutions acted as engineering indicators and highlighted …

A preliminary study of the solubilization of wool and separation of soluble wool into protein classes : this thesis was presented in part fulfilment of the requirements for the degree of Master of Science in Chemistry at Massey University
… soluble wool protein. Data are reported on foam fractionation conditions of pH, concentration, sparging gas and desalting. Wool was reduced and solubilized using sodium sulfide. The soluble product was processed under nitrogen and proved unstable in air. Thin films were produced from …

Molecular Design Of Lanthanide Binding Tag Peptides For Nanoparticle Assisted Interfacial Separation Of Rare Earth Elements
… slight surface activity, can be recovered via foam fractionation. However, this approach is limited by poor foam stability and the formation of wet foam which negatively impacts selectivity. To address these challenges, we introduce positively aminated silica nanoparticles (NPs), which …
