Immobilization of NanoFe3O4 onto fabric material through in situ co-precipitation as a flexible catalyst for humic acid degradation

Humic acid (HA) is a major component in dissolved natural organic matter (NOM) that is commonly found in natural water sources such as surface water and soil. Although HA is non-toxic, it is a precursor of carcinogenic and mutagenic disinfection by-products that will be generated when chlorine and c...
