where C0 is the initial dye concentration in liquid phase (mg L−1), C e is the liquid-phase dye concentration at equilibrium (mg L−1), V is the volume of the dye solution used (L), and m is the mass of the adsorbent used (g).
The percentage of dye removal at equilibrium was calculated using Eq. (3): {text{Removal}},left( % right) = frac{{C_{0} - C_{text{e}} }}{{C_{0} }},, times,100 (3)where C o and C e are the liquid-phase dye concentrations at initial and equilibrium states (mg/L), respectively.
By confocal microscopy, we monitored the intracellular distribution of the membrane-impermeable liquid-phase dye LY.
This difference was related to the higher affinity of CV for the adsorbent surface than FG and may also be attributed to a tendency for the dye molecules to escape from the solid phase of the modified clay to the liquid phase of dye with an increase in temperature of the solution.
The amount of adsorption at equilibrium, q e (mg/g), was calculated by: q_{text{e}} = frac{V}{W} ( C_{0} - C_{text{e}} ) (1 where C 0 and C e (mg/L) are the liquid phase concentrations of dye at the initial and equilibrium conditions, respectively.
22 197-1 20077) as well as in liquid phase by decolorization of organic dyes e.g. methylene blue (MB) and rhodamine B (RhB).
Initial dye concentration in liquid phase (mg L−1).
In its classical version, PLIF consists in viewing the presence of a fluorescent dye in a liquid phase by means of a laser sheet.
The resulting liquid phase was used to determine the residual dye concentration by colorimetric method.
A fluorescent dye dissolved in the liquid phase allows to identify in-plane bubbles among all visible bubbles in the images.
