TREATMENT OF TEST MATERIAL PRIOR TO TESTING
- Treatment of test material prior to testing (e.g. warming, grinding):
- Preliminary purification step (if any):
- Final concentration of a dissolved solid, stock liquid or gel:
- Final preparation of a solid (e.g. stock crystals ground to fine powder using a mortar and pestle): Since Ammonium hexafluoroantimonate was not sufficiently soluble to allow preparation of an aqueous solution at a concentration of 1 g/l, weighed amounts of Ammonium hexafluoroantimonate were added to the test bottles (2 litres) containing medium with microbial organisms and mineral components (test substance bottle A: 60.6 mg; test substance bottle B: 60.7 mg and toxicity control bottle: 60.5 mg). To this end, 10 ml of MiMi-RO water was added to each weighing bottle containing the test substance. After vigorous shaking the resulting suspension was added quantitatively to the test medium. The test solutions were continuously stirred during the test, to ensure optimal contact between the test substance and the test organisms.
