摘要：我国是全世界最大的染料生产国家之一，这就导致了染料工业的基数过于庞大，进而导致了产生的废水的量也非常巨大，这些废水中的污染物浓度大，种类较多，结构相对复杂，自身可生化性差，国内如今并没有非常成熟的可以处理所有废水的工艺，所以这就导致了大多数的染料废水无法处理，只能直接排放或暂存。日积月累，使得工业染料废水成为了当今国家最主要的污染来源之一。

电催化氧化法可以把有机物降解的更彻底，而且其间不易产生有毒的物质，基本上避免了第二次污染。电催化氧化法的可控性强、设备简单、运行方便，所以近年来电催化氧化法在废水处理过程中十分常见而且运用广泛。

本实验通过分析不同热解温度下的极化曲线、析氧曲线和循环伏安曲线析氧曲线，来探究Mo掺杂Sn-Sb电极反应的性质、机理和电极过程动力学参数的研究。通过制备Mo掺杂Sn-Sb电极处理柠檬黄废水，考察了pH值、电压、电解质浓度、电解时间、使用次数、柠檬黄浓度、板间距等对电催化性能的影响。实验结果表明：当pH值为中性，电压为15V，电解质浓度为300mg/L，电解时间为20min时，板间距为1.5cm处理效果达到最佳，对20mg/L柠檬黄废水的去除率达94%以上。

Abstract：China is one of the world's largest dye producing countries, which led to the dye industry base is too large, resulting in the waste water quantity is very huge, the concentration of pollutants in the wastewater is large, many types, the structure is relatively complex, its poor biodegradability, China now does not process can handle all the wastewater is very mature, so this leads to the majority of the dye wastewater can not be processed, only direct emissions or temporary. Over a long period of time, industrial dye wastewater has become one of the most important sources of pollution in the country.

Electro catalytic oxidation can degrade organic matter more thoroughly, and it is not easy to produce toxic substances, and basically avoid second pollution. Because of its high controllability, simple equipment and convenient operation, the electrocatalytic oxidation process has been widely used in wastewater treatment recently and has been widely used.

In this experiment, through the analysis of the polarization curves at different pyrolysis temperatures, oxygen evolution curves and cyclic voltammetry curves of kinetic parameters of oxygen evolution, nature, and to explore the mechanism of the electrode process of Mo doped Sn-Sb electrode reaction. The citric acid wastewater was treated by Mo doped Sn-Sb electrode. The effects of pH value, voltage, electrolyte concentration, electrolysis time, number of times, concentration of citric acid and pitch on electrocatalytic performance were investigated. The experimental results show that when the pH value is neutral, the voltage is 15V, the electrolyte concentration is 300mg/L, the electrolysis time is 20min, the plate spacing is 1.5cm, the treatment effect is the best, and the removal rate of 20mg/L Tartrazine Wastewater is more than 94%.
