Abstract: | The influence of mesquite gum on the interfacial tension between liquid paraffin and distilled water has been studied as a function of gum concentration, pH, and added NaCl or CaCl2. The time dependence of the reduction in interfacial tension was influenced by all three variables. Diffusion to the oil-water interface was the dominant factor in the initial decrease of interfacial tension when low mesquite gum concentrations were used. Reconformation of molecules adsorbed at the oil-water interface controlled the reduction in interfacial tension at longer times when using more concentrated gum solutions. |
