Medications excreted in the urine or dumped into the toilet can end up in the water supply, just like lotions or cosmetics that wash off the body and go down the sink or shower drain. Unfortunately, conventional wastewater treatment cannot completely remove pharmaceuticals and personal care products (PPCPs). Now, researchers reporting in ACS Applied Materials & Interfaces have developed an adsorbent membrane that they say could be used to purify water contaminated with PPCPs.
