2.2. Fresh leachate
The fresh leachate used as the feed in this experiment was
obtained from a MSW incineration plant in Beijing, China. The
water composition of the leachate is shown in Table 1. The feed
solution was adjusted to a pH of 5.8–6.0 by adding 1 mol/L NaOH
or 1 mol/L HCl solution and then stored at 4 C in a refrigerator.
