Results and discussion
Any other information on results incl. tables
Parent substance (Molyvan 855J):
The test substance itself was found to be almost completely eliminated in the experimental study and so a direct compartmental distribution for the substances cannot be shown. It can be, however, indirectly inferred as predominating to the aqueous phase based upon the analysis of the compartmental distribution of the degradates.
Molybdic acid:
Molybdic acid is detected entirely in the aqueous phase with nothing detected in the organic phase. These species were also found in a comparative test run with pure water only, though at a lower percentage level.
Organic molybdenum species:
Organic molybdenum species were not found during this analysis and hence are not present at any significant level. These species were found in a comparative test run with pure water only.
Structurally modified organic substances:
Structurally modified organic substances were detected in the aqueous phase and at concentrations which showed a mass balance with degradation rate of the parent substance. These substances were not detected in the organic phase. The compartmental distribution of the structurally modified organic substances is considered, therefore, to be predominately to the aqueous phase.
Discussion:
Important differences are found between the behaviour of the substance in purified water compared with aqueous media containing biotic matter. The primary difference is, that presence of biotic matters seems to eliminate organic molybdenum species in favour of molybdic acid and structurally modified organic species; and this leads to a compartmental distribution which predominates in the aqueous phase with negligible matter in the organic phase.
Proposed compartmental distributions:
Molyvan 855J: Water 100%, sludge 0%
Molybdic acid: Water 100%, sludge 0%
Structurally modified organic substances: Water 100%, sludge 0%
