RECYCLABLE POROUS MATERIALS FOR THE UPTAKE OF BISPHENOL A

The presence of pollutants in the environment, food, drinking water and other compounds in direct or indirect contact with humans is a major environmental issue. In this regard, a privileged place reverts to the capture or decomposition of pollutants without producing traces of residual toxins. An i...
