At any of the time points mentioned in the TG-318, the influence of Ca
is critical. Regardless of pH, the pigment is categorized at the
24h-sampling time as “unstable” in 10 mM Ca, representing high water
hardness.
After 6h, the stability for the samples in 0 mM Ca and at pH 4, 7 and 9
was high.
For the samples in 1 mM Ca at pH 4 the stability increased to an intermediate level after 24 hours, whereas at pH 7 and 9 the pigment was stable.
The Full results of the dispersion stability in the presence of NOM is presented in following table

To rationalize the observed dispersion stability, we finally checked the
particle size distribution directly in the environmental medium (exact
same sample preparation as for the UV/VIS measurements). We applied the
NanoDefine method of Analytical Ultracentrifugation (SOP AUC-RI,
published by 3). The centrifugation parameters are given in the methods
section.
The observed size distributions confirm the moderate agglomeration at 1
mM Ca, pH7, with NOM (Figure 4). If the particles would have been
significantly dissolved, no size distribution would be observable at all
by this method, which relies on the detection of the movement of
particles during centrifugal separation.
Additionally, the centrifugation methods include a determination of the
remaining absorption after centrifugation, fully consistent with the
conventional determination of the dissolved fraction after
centrifugation as recommended by the TG-318. The remaining absorption
was measured at c.a 0.014. This is a fraction of 1.7% of the initial
absorption, but actually is close to the LOD of the built-in UV/Vis
detector. Considering the LOD, between 0% and 1.7% of the sample may
have been dissolved.
All evidence combined, the results after centrifugation confirm that at
least 98.3% of the observed dispersion stability has to be attributed to
the particles, not to dissolution.
