Environmental Chemistry

Environmental chemistry is the research area that monitors emissions of air toxics, clean water supply, global environmental change and waste disposal (including hazardous and radioactive waste management). As aesthetics, economics, recreation, and other elements of better, healthy and safe living become essential issues and have become part of the responsibilities of the modern engineer and scientist, environmental chemistry has risen in importance. In order to minimize and/or eliminate the environmental issues, one has to have great knowledge about chemistry, mechanisms of chemical reactions, flow of energy and materials through the ecosystem and production system. On this occasion, chemistry and materials science have crucial role on decreasing the environmental fates of materials, processes

In Sabancı University, environmental chemistry research is focused mostly on heavy metal removal and membrane technologies.

Membrane Technologies

Membrane technologies which are in high favor is being studied. In order to get mechanically and chemically stable, reusable, low energy requiring and cost-effective membranes material development and research plays an crucial role. On that occasion, several studies have been conducted.

  • Modified polyether ether ketone (PEEK-WC) membranes for ultrafiltration.
    Preparation and characterization of modified polyether ether ketone (PEEK-WC) membranes for polymer assisted ultrafiltration of Cu2+ ions from water (2014)
  • Zeolite membranes for metal ion removal.
    Preparation and characterization of modified polyether ether ketone (PEEK-WC) membranes for polymer assisted ultrafiltration of Cu2+ ions from water (2014)

Water Management Studies

It is pretty clear that water severity could not be solved by only developing new technologies to treat the water that has been polluted. It is important to know how much water is used in which process to decrease the water consumption. Accordingly, the following study is conducted.

  • Water footprint assessment of Sabanci University.
