Winter's (1972) study showed that ferric hydroxide floccules
at concentrations above 1.0 mg [L.sup.-1] caused a mortality of 75% over 3 mo and 0.4 mg [L.sup.-1] caused a mortality of 40% over 5 mo.
All oysters removed from Treatments 4 and 5 displayed gross signs of iron floccules in the shell fluid and on the gill surface.
Iron floccules were observed grossly in oysters removed from field sites exposed to ASS-affected waters (Dove & Sammut in press).
Murine monoclonal antibody adsorbed onto vinylidene fluoride floccules
used to eliminate antibody interference in "sandwich"-type immunoassays.
1, the R value (B) of the total CS absorbed to stearic acid was appreciably higher than that (C) after the floccules
were washed with anhydrous diethyl ether and the ratio (A) of n([COO.sup.-])/n([NH.sub.3.sup.+]).
The formation of large floccules
also increased the settling rate of the fine solids in the tailings.
However, they provided no evidence that the clay crystals in the entities formed were in parallel or near parallel alignment, so they were probably investigating the characteristics of floccules
rather than clay domains as they suggest.
They show well-developed floccules
due to the cementations.
The floc density [[rho.sub.f], a key parameter in assessing the floccules
sedimentation rate, can be calculated through the following relation:
The chemical oxidation stability of the membranes was estimated by the appearance time of floccules
of the small pieces of the membranes in Fenton reagent (a 3% [H.sub.2][O.sub.2] aqueous solution containing 2 ppm [FeSO.sub.4]) at 80 [degrees]C (22).
