Research: Membrane Removes Pharmaceuticals from Water

To remedy wastewater treatment plants’ inability to completely remove pharmaceuticals and personal care products (PPCPs) from the water supply, researchers based out of Northeast Normal University recently developed an adsorbent material for the removal of PPCPs.

The paper, titled “Porous Aromatic Framework Modified Electrospun Fiber Membrane as a Highly Efficient and Reusable Adsorbent for Pharmaceuticals and Personal Care Products Removal,” was published in ACS Applied Materials & Interfaces.

PPCP Removal

According to the American Chemical Society, due to an increased quality of life across the globe, there has been a similar upward trend in the presence of PPCPs in surface water and groundwater, as well as fish and vegetable tissue. Danger arises from the fact that some PPCPs are endocrine disruptors or could otherwise potentially have a negative impact on health and/or the environment.

To remedy wastewater treatment plants’ inability to completely remove pharmaceuticals and personal care products (PPCPs) from the water supply, researchers based out of Northeast Normal University recently developed an adsorbent material for the removal of PPCPs.

Research indicates that though porous aromatic frameworks can remove these things, PAFs do not dissolve in most solvents, as they are in powder form. This makes handling and disposal through recycling difficult.

Researcher Guangshan Zhu, working with colleagues from the university, developed an adsorbent material to address this issue by electrospinning a polymer known as polyacrylonitrile into a fibrous membrane. This was then coated with polyaniline so that PAFs would attach to the surface.

Biphenyl molecules were then added, which were reacted to grow PAF-45 on the polyaniline-coated fibers. As a result, the modified membrane was able to adsorb ibuprofen, chloroxylenol and diethyl-meta-toluamide (DEET), otherwise known as three model PPCPs.

The membrane is also recyclable: The membrane was also reusable for 10 adsorption-desorption cycles with a slight decrease in capacity. The research team was also able to use ethanol to remove the adsorbed PPCPs.

Research funding was provided by the National Natural Science Foundation of China and the Fundamental Research Funds for the Central Universities.
