Table 4.
Qualitative flotation/sinking behavior of cresol-rich droplets in turbid mixtures aged 10 days (2 wt% cresol; salt concentrations as indicated). Where present, “entrained with flocs” denotes droplet-floc aggregates at the vessel bottom
| Salt type | 0.1 M | 0.5 M |
|---|---|---|
| NaCl | N/A | Droplets floated |
| ZnCl2 | Some droplets floated, others were entrained with flocs at the bottom | |
| ZnSO4 | ||
| CuCl2 | All droplets sank | Droplets sank |
| CuSO4 | Some droplets sank, others floated | Droplets floated |
| FeCl2 | Some droplets floated, others were entrained with flocs at the bottom | |
| FeSO4 | ||
