羟胺是典型的显影剂和防氧化剂,研究它的氧化反应机理是很有意义的。前文在HAc-NaAc(pH-3.9—5.0)介质中的研究发现,当Σ[Fe~(3+)]<3×10~(-6)mol·L~(-1)时,铁离子催化十二钨酸络钴酸钾K_5[CoW_(12)O_(40)](简记为Co~3+W)氧化羟胺的反应遵循(1)式:
Hydroxylamine is a typical developer and anti-oxidant, the study of its oxidation reaction mechanism is of great significance. In the previous study of HAc-NaAc (pH-3.9-5.0), it was found that ferric ion catalysis catalyzed by [Fe 3+] <3 × 10 -6 mol·L -1 The reaction of potassium tungstate with potassium tungstate K_5 [CoW_ (12) O_ (40)] (abbreviated as Co ~ 3 + W)
