| description | Background: High amount of heavy metals in sludge is one
of the major obstacles to its use on farms. The present study
aimed to investigate the possibility of leaching heavy metals
from wastewater sludge by Fenton method and determine the
optimum level of parameters, such as iron, hydrogen peroxide,
time, and pH for Fenton reaction.
Methods: The effects of various parameters, such as pH (2-9),
hydrogen peroxide concentration (0.5-6 g/l), Fe concentration
(0.5-4 g/l), and leaching time (5-60 min), were studied.
Results: The results showed that the optimal condition for
leaching of heavy metals occurred at pH of 2-3, hydrogen
peroxide concentration of 3 g/l, iron concentration of 2 g/l, and
leaching time of 15 min. Under these optimal conditions, 92%
of Zn, 100% of Cd, 100% of Pb, and 80% of Cu were leached
from the wastewater sludge.
Conclusions: Fenton method can leach heavy metals from
wastewater sludge through decomposition of organic materials
at H2O2/Fe ratio of 1.5:2. |
