Abstract:

This dataset reports the volume, number, surface tension, interfacial tension, and adsorption coefficient for quartz sand aggregates in different hydrophobic liquids over time. Various hydrophobic liquids (decane, tetradecane, hexadecane, benzene, toluene, ethylbenzene, m-xylene, and 2-chlorotoluene) were added to either deionized or salt (34 ppt) water. Quartz sand was then added to the surface of these hydrophobic liquids in water. The quartz sand formed aggregates which were observed over the course of 10 days. This dataset supports the paper: Daria Boglaienko and Berrin Tansel (2016) Encapsulation of light hydrophobic liquids with fine quartz sand: Property based characterization and stability in aqueous media with different salinities, Chemical Engineering Science, 145, 90-96, doi: 10.1016/j.ces.2016.02.010.

Purpose:

To observe the properties of hydrophobic liquids in salt and deionized water.

Methods:

1 g (+/- 0.01 g) quartz sand (0.075 mm - 0.425 mm) was added to 50 mL (+/- 0.06 mL) of a hydrophobic liquid and 100 mlibeL of salt water (34 ppt) or deionized water. When added to the hydrophobic liquids, sand particles aggregated on the surface. These aggregates were monitored for 10 days. The number of aggregates and volume of aggregates was observed. Vapor pressure calculated by equation: log10 Pv = A+B/T +C log10T + DT +ET2.
