Antioxidants stabilize the colouring solution by preventing Sn~ ( 2+) from oxidation and increase the colouring reproducibility by promoting cathodic reduction processes. Their effect on throwing power is not notable. 抗氧化剂遏制Sn~(2+)氧化而稳定槽液,促进阴极还原过程而提高着色重现性,但对分散能力影响不明显。
The experimental results suggest that complexing agents influence the stability of colouring solution through affecting the complexing equilibrium between Sn~ ( 2+) and Sn~ ( 4+), and influence the throwing power and colouring reproducibility by affecting cathode surface reactions. 认为:络合剂影响稳定性的本质是对Sn~(2+)、Sn~(4+)络合平衡的影响,同时通过影响阴极界面反应来实现对分散能力及着色重现性的影响;
