Figure 2: Influence of contact time on the Ag+sequestration at TF-VO loading of 3.5 g per 20 mL of contaminated water
Furthermore, to ascertain the liquid-liquid equilibrium contact time,
the influence of contact time on Ag+ sequestration at
TF-VO loading of 3.5 g per 20 mL of contaminated water, was investigated
and the result is as shown in Figure 2. From the figure, TF-PKO quickly
attained a stable extraction efficiency after 4 hours, while other TF
oils reached 6 hours. A general equilibrium contact time of 6 hours was
chosen and used hereafter.
