Considering the stricter European regulations for chemical pesticides (e.g. abolishment of the use of chemical soil fumigation products, such as methyl bromide), the need for more sustainable plant protection products is strongly increasing. In this research, Product X, an innovative mixture of bio...
quadricauda removal of a mixture of sulfonamides, macrolides, fluoroquinolones, and trimethoprim were the worst among the four microalgae studied, with a mean removal efficiency of 47 % [19]. Interestingly, the removal of veterinary drugs and other antibiotics by S. quadricauda, used as a ...
Poly(acrylic acid) or PAA (CAS number 9003-1-04) is a type of polymer. The monomer of poly(acrylic acid) is Acrylic Acid. In a water solution at neutral pH, many of the side chains of PAA will lose their protons and acquire a negative charge. For a description of unrelated compound...
