Homogeneous cobalt-activated peroxymonosulphate reaction (Co2+/PMS) was applied to decolorize Rhodamine B (RhB) and Acid Yellow G (AYG) and the main experimental parameters (nitrate cobalt concentration, PMS dosage, pH) were investigated. At the optical condition (1 mg/L Co(NO3)2, 20 mg/L PMS and pH=7 for RhB; 10 mg/L Co(NO3)2, 65 mg/L PMS and pH=9 for AYG ), the colour removal of RhB and AYG were 99.5% and 98% respectively. Plus, Mn+/PMS process (Cu2+/PMS, Mn2+/PMS, Ni2+/PMS, Fe3+/PMS, Fe2+/PMS) was carried out to study the catalytic effect of similar activators with same molar concentration. The evidence indicates that Fe2+ and Cu2+ ion are more reactive compared to other ions, while that catalysis is still incomparable to cobalt ion. Furthermore, in Co2+/PMS process, the acid dyes (Acid Red 6B, Acid Yellow G, Acid Blue) were found to become more degradable at alkaline condition (pH 9) than neutral solution.Keywords
