As shown in Fig. X, the presence of ClO4− (10 mmol) enhanced the RhB degradation, revealing that there existed a strong inner-sphere interaction between the S2O8- and the active sites on the catalyst surface. The enhanced oxidation efficiency may due to the high oxidation potential of perchlorate (1.389 V). However, the presence of 10 mmol NO3−, HCO3− or H2PO4− exhibited different degrees of inhibition effect. These anions are considered as radical(such as SO4•−  quenchers. （特別是下邊這幾句，能改的地方感覺(jué)很少  ）NO3−can rapidly react with SO4−at the rate constant of 8.8 × 108 M−1s−1 .HCO3−can also rapidly react with SO4•−and HO• to produce the HCO3• at the rate constants of 1.6 × 106 M−1s−1and 8.5 × 106 M−1s−1, respectively, while H2PO4− reacts with SO4•− and HO• to produce the H2PO4• at the rate constants of ＜ 7.2 × 104 M−1s−1and 2.0 × 104 M−1s−1, respectively. The obtained active species such as NO3•,HCO3• and H2PO4• would compete with HO• or SO4•−for reaction with RhB, resulting in decreasing the RhB decolorization efficiency.英語(yǔ)太爛啊  |

It can be seen in Fig. X that, the presence of ClO4− (10 mmol) boosted the RhB degradation, demonstrating that a strong inner-sphere interaction existing between the S2O8- and the active sites on the catalyst surface. The higher oxidation efficiency may contribute to the high oxidation potential of perchlorate (1.389 V). However, the 10 mmol NO3−, HCO3− or H2PO4−present in the reactants demonstrated different degrees of inhibition effect. These anions are radical as considered (such as SO4•− quenchers. 你是說(shuō)的這種paraphrazing? 拋個(gè)磚 |
