Sodiumalginate/polyethyleneiminehydrogel: Aneffectivematerial for theadsorption
of heavy metal ions in water and catalysis

W
ater pollution created by heavy metal ions becomes
worldwide concern because of indiscriminate
disposal of industrial wastewater in pure water system.
In this work, we report a natural and highly efficient
sodium alginate (ALG)/polyethyleneimine (PEI) composite
hydrogel fabricated by a chemical crosslinking method for
the removal of heavy metal ions from wastewater. The
adsorption of heavymetal ions was thoroughly investigated
in single ion adsorption and multi ions adsorption systems.
In addition, after the adsorption we in situ reduced the
Cu+2 ions forming a Cu NPs-loaded hydrogel, which proved
an excellent catalyst as evidenced by the reduction reaction
of 4- nitrophenol. We believe that the as-prepared ALG/PEI
hydrogel will present an effective and practical paradigm
for the cascaded treatment and recycling of heavy metal
ions in wastewater.
