Degradation of fuchsine acid using the HP2W15Mo3Co2.5O62, 20H2O/H2O2 system: effect of organic and inorganic additives
Autor: Selma Bencedira, Ouahiba Bechiri
Publikováno v: Euro-Mediterranean Journal for Environmental Integration. 6
This study aimed to evaluate the influence of mineral and organic additives on the catalytic oxidation of the dye fuchsine acid by the HP2W15Mo3Co2.5O62, 20H2O/H2O2 system. Initially, the effects of various organic additives, namely alcohols (methano
