- The adsorption behaviors of an ether amine surfactant, N1-(3-((8-methyl-nonyl)oxy) propyl)propane-1,3-diamine, on collophane and quartz were studied. Batch adsorption experiments were conducted to characterize the thermodynamic behavior of the adsorption process and to calculate the maximum adsorption. Results demonstrated that the adsorption of the ether amine on quartz was greater than collophane. Adsorption mechanisms were studied by means of contact angle measurement, zeta potential measurement, FT-IR analysis, and X-ray photoelectron spectroscopy. The results showed that the adsorption of the ether amine surfactant on quartz surface was easier and more efficient than collophane. Micro-flotation tests testified that the collector can efficiently separate collophane from quartz at room temperature in neutral medium.
