| 摘 要： | 采用Fe0还原、钯催化法对偶氮染料———酸性紫红B进行还原脱色研究,测定了钯/铁及普通铁粉在相同条件下对酸性紫红B的还原降解反应速率常数.实验表明,酸性紫红B的零价铁及钯/铁催化还原降解均遵守一级动力学,且钯/铁的反应速率常数较普通铁粉有明显增大.

| Abstract: | The reductive degradation of acid violet red B by palladium/iron(Pd/Fe)is measured.The degradation of acid violet red B on the Pd/Fe and that on the conventional iron powder are compared. It was found that the catalytic degradation of acid violet red B on the Pd/Fe and the zero-valent iron follow the first-order kinetics and the rate constant on Pd/Fe is higher than that on the conventional iron powder, |

| Keywords: | first-order kinetics constant Pd/Fe Fe~(0) reduce acid violet red B |
