pH 5 buffer solution: 0.12 mg/L
pH 7 buffer solution: 0.11 mg/L
pH 9 buffer solution: 0.11 mg/L - Executive summary:
The solubility of the test substance was determined in purified water and buffer solutions at pH 5, 7 and 9 following the guidelines OECD Guideline 105, EU Method A.6 and EPA OPPTS 830.7840. Preliminary tests to measure the solubility were performed by stirring known masses of test substance with known volumes of either purified water, pH 5, 7 or 9 buffer solutions for 96 hours. At this stage, further preliminary work was conducted in which samples from the tests were analysed by a chromatography method. The solubility was subsequently determined by the column elution method.
The following solubilities were determined for the test substance at 20°C:
Purified water: 0.12 mg/L
pH 5 buffer solution: 0.12 mg/L
pH 7 buffer solution: 0.11 mg/L
pH 9 buffer solution: 0.11 mg/L
