The decomposition of AO7 under various conditions are demonstrated in Fig. 1a. Cu(II) or SPC alone could barely degrade AO7, indicating weak capability to decompose AO7 by Cu(II) or SPC, consistent with the previous results reported [20]. Remarkably, the co-presence of Cu(II) and SPC in the system resulted in relatively fast decolorization of AO7, with approximately 90% of AO7 degraded in the first 2 min, and around 95% of AO7 was removed within 15 min, suggesting the triggering effects of SPC

In recent years, activation of sodium percarbonate (SPC) has been regarded as very appealing technologies in the elimination of organic pollutants. In this work, the activation of SPC using micro amounts of Cu(II) (at & mu;M level) towards acid orange 7 (AO7) degradation was explored. Experimental results displayed that nearly 97.5% of AO7 could be removed within 15 min using 20 & mu;M Cu(II) and 0.4 mM SPC. Effects of Cu(II) concentration, SPC concentration, pH value and coexisting anions were investigated. Compared with conventional Fenton oxidation, which could only work under acidic pH con...
