Electrochemical and photoelectrochemical treatment of 1-aminonaphthalene-3,6-disulphonic acid

Electrochemical treatment of aqueous solutions containing urea

“…Electrochemical methods can be used for the neutralization of cyanides [8,9], phenols [10,11], chlorophenols [12][13][14], trichloroethylene [15], herbicides [16], poorly-degradable organic compounds [17], landfill leachate [18], and others. Electrochemical wastewater treatment can also be successfully applied in tanneries [19][20][21], olive-oil production plants [22], textile industry [23][24][25][26][27], and in distilleries [28]. The process of electrochemical decomposition of urea on dimensionally stable electrodes covered with ruthenium and titanium oxides has been applied for the purification of dairy manure lagoon water [29].…”

Photoelectrochemical treatment of 1-amino-8-hydroxynaphthalene-3,6-disulphonic acid at electrode covered with TiO/RuO

“…In the case of reactive dyes and 1-aminonaphthalene-3,6-disulphonic acid, combination of the electrochemical oxidation with the photocatalytic degradation yields in higher effectiveness of the treatment method [8,9]. Thus, the application of these two combined methods can be suggested for treatment of especially toxic H acid.…”

Electrochemical degradation of aromatic amines on BDD electrodes

“…The anodic oxidation of few aromatic amines have been studied on different anode materials and under different conditions: Pt anode was used in the electrodegradation study of aniline [16], chloroanilines [17] and 5-amino-6-methyl-2-benzimidazolone [18]; 4-amino-dimethyl-aniline hydrochloride was electrodegraded with a Ti/Ru-Ti-Sn ternary oxide coated anode [19]; Pt and Ti-TiO 2 /RuO 2 were used to degrade 1-aminonaphthalene-3,6-disulfonic acid [20]. BDD anodes were also used in the anodic oxidation of aromatic amines, like aniline [21,22], sulfanilic acid and 1-amino-2-naphtol [23], ortanilic, metanilic and sulfanilic acids [22], p-aminophenol [24] and naphthalenesulfonates [25].…”
