azardous waste disposal is one of the biggest environmental issues of last decades. Incineration is a way to disposal of
hazardous wastes and has many advantages beside disadvantages. One of the most important disadvantages is effluents
which contain heavy metal ions as pollutants. Unlike some other organic pollutants, heavy metals are nonbiodegradable,
highly toxic and carcinogenic. In addition, due to their high solubility in water, even very low concentration results in
ecological problems, so it is necessary to remove these ions. Different methods or materials have been used, new techniques
and materials have been tried to develop or improve to find more effective ways to remove such ions from wastewater.
Hydrogels are crosslinked hydrophilic polymers that are widely used in the purification of wastewater. Due to their high
swelling in water, ability to control the diffusion process, swelling response to changes in ionic strength, pH and temperature
and also the capability to bind heavy metal ions through the polar functional groups which interact selectively and strongly
with heavy metal ions, moreover easy handling and reusability make hydrogels promising materials for water purification.
Macroinimer which has the properties of macromonomers, macrocrosslinkers and macroinitiator in a macrostructure, was
used to prepare novel hydrogels with higher metal binding capacity than present hydrogels. Novel hydrogels were prepared
by oil-in-water high internal phase emulsion copolymerization of 2-hydroxy ethylmethacrylate, N-isopropylacrylamide
and N,N'-methylenebis(acrylamide) as crosslinker at room temperature. Macroinimer was used as co-surfactant and co-
crosslinker. Varying amounts of N-isopropylacrylamide and macroinimer were used to prepare hydrogels. Swelling properties
of all hydrogels was investigated at different temperatures. Also hydrogels were used as binding materials for different heavy
metals such as Pb, Cr and Hg from hazardous waste incineration plant effluent to identify the best fitting hydrogel composition
for heavy metal ion binding capability.
Biography
Ömer F Kemik is a Chemist from Kocaeli, Turkey. He graduated from Kocaeli University with MSc degree in Chemistry in 2009. He is currently PhD student
at Kocaeli University and also works for İZAYDAŞ which is the only hazardous waste incineration plant of Turkey. He has expertise especially in hydrogels for
environmental purposes and proficiency testing in wide scope.
