Individual Results
Preliminary Visual Estimation of the Water Solubility
Table: Appearance of the test mixtures in the preliminary test
Amount of the test item in mg | Total volume in ml | Appearance of mixture |
10 | 10 | Undissolved |
50 | Undissolved |
The preliminary visual experiments showed that the water solubility of the test item is very low.

Table 2: Water solubility of the test item – experiments A to D
Experiment | A | B | C | D(blank) |
Amount of test item(mg) | 500 | 500 | 500 | --- |
Stirring time at 30°C (h) | 24 | 48 | 72 | 72 |
Measured concentration (μg/l) | 3079 | 3187 | 3257 | n.d. < 0.13 |
Water solubility (mg/l) | 3.08 | 3.19 | 3.26 | --- |
Average experiments A to C: 3.18 mg/l
Table: Standard addition for recheck:
Standard | Measured concentration (mg/l) | % Recovery |
Sample C + 1.31 µg test item | 1.35 | 103.0 |
The recovery of 103.0 % indicates a sufficient accuracy of the analytical method.
