From: Decontamination of water co-polluted by copper, toluene and tetrahydrofuran using lauric acid
SAXS patterns of lauric acid in either 100% THF, or in THF-water mixtures, with 95% THF or 90% THF (at either acidic or circum-neutral pH) relative to water (v/v) and 500 g/L lauric acid. The experimental data are shown in red, and fit to the Steubner and Strey model (continuous black line) or a Gaussian (dashed line). The Ornstein and Zernicke fit (dotted line) is poor, and shown as a reference. The best fitting parameters of the Ornstein and Zernicke model are as follows: 100% THF: a2 = 0.6572, c1 = 152.8; 95% THF, neutral pH: a2 = 0.6366, c1 = 167.0; 90% THF, neutral pH: a2 = 0.6402, c1 = 173.0; 90% THF, acidic pH: a2 = 0.6249, c1 = 175.9. The Teubner and Strey best fitting parameters are as indicated in Table 4.
