(Elsevier, 2024)[Abstract] The use of carotenoids, pigments with significant importance in the food and pharmaceutical industries, has been widely recognized because of their functions as colorants and antioxidants. The production of ... -
Characterization of absorbent polymers for the removal of volatile hydrophobic pollutants from air
Montes, María; Daugulis, Andrew J.; Veiga, María Carmen; Kennes, Christian (Wiley-Blackwell, 2011-01)An emerging innovation for the treatment of polluted air consists in using a liquid–solid biphasic system, in which the sequestering phase contains inert polymer beads. The different polymers tested here for this purpose ... -
