Additional information
The water solubility of trimanganese bis(orthophosphate) was determined using the flask method (loadings of test item of 26.644 mg/L and 26.352 mg/L in vessel 1 and 2, respectively) acoording to OECD 105 and EU method A.6 (Klawonn & Knopf, 2018). The mean amount of dissolved test item according to the measured manganese after day 36 – 38 was 13.9 ± 0.85 for vessel 1 and 13.8 ± 0.43 mg/L for vessel 2 (mean 13.8 ± 0.64 mg/L).
In further studies, the water solubility of trimanganese bis(orthophosphate) and hureaulite was determined using the flask method acoording to OECD 105 and EU method A.6 (Klawonn & Knopf, 2018). The mean amount of dissolved test item (trimanganese bis(orthophosphate) and hureaulite) according to measured manganese were 12.1 ± 1.12 mg/L and 9.85 ± 0.54 mg/L.
The water solubility of trimanganese bis(orthophosphate) was determined using the flask method in a study conducted according to EU Method A.6 under GLP conditions (Butler and O'Connor, 2010). The water solubility of the test material was determined to be 9.31 mg/L at 20.0 ± 0.5 °C in un-buffered glass double-distilled water, resulting in sample solution pH’s of approximately 7.1 to 7.6.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
