Abstract:
|
Advance oxidation process was employed as a pretreat-
ment of industrial wastewater. For this purpose, the use of
heavy metals as a catalyst is necessary but also complicated
because homogeneous catalysts are difficult to recover after
reaction process. The heterogenization of Cu(II) ions was
proposed by taking advantage of the adsorptive characteris-
tics of polymeric matrices. Crosslinked poly(4-vinylpyridine)
of 2 and 25% and poly(
D
-glucosamine) were tested as sup-
ports of copper. Adsorption was employed to heterogenize
Cu(II) by considering the influences of pH and temperature
on the process. The catalysts were evaluated by their metal
content, catalytic behavior for the oxidation of phenol and
leaching degree after reaction. Poly(4-vinylpyridine) 2% was
the best material for Cu(II) immobilization with an adsorp-
tion capacity of 90 mg g

. Afterward, poly(4-vinylpyridine)
2%, Cu(II) achieved 64% of phenol conversion, which repre-
sents a favorable result for the oxidation of phenol as the
model of industrial wastewater pretreatments. |
