activated carbon; adsorption; biocides; biofouling; fabrics; hydrophobicity; octanol; pH; partition coefficients; reverse osmosis; sorption isotherms
Abstract:
... Isothiazolones have been widely applied as non-oxidizing biocides to prevent biofouling of reverse osmosis (RO) membranes. However, few studies have investigated suitable RO concentrate treatments to remove these biocides. This study evaluated the adsorption behavior of four isothiazolone biocides, 2-methyl-4-isothiazolin-3-one (MIT), 5-chloro-2-methyl-4-isothiazolin-3-one (CMIT), 1,2-benzisothiaz ...
