文章应用循环伏安法(CV)研究了邻苯二酚(CC)、对苯二酚(HQ)和间苯二酚(RS)在多壁碳纳米管修饰的玻碳电极(MWNTs/GCE)表面的电催化氧化行为,同时对pH、扫描速度、温度等试验条件的影响也进行了研究。结果表明:MWNTs/GCE电极对CC、HQ和RS均表现出较好的电催化和电分离作用;在高浓度HQ和RS存在条件下,CC的氧化峰电流在0.05～7.00mmol/L范围内与浓度呈良好的线性关系,相关系数R~2=0.9989;修饰电极实现了对实际废水中苯二酚三种异构体的同时测定。
Cyclic voltammetry (CV) was used to study the effects of catechol (CC), hydroquinone (HQ) and resorcinol (RS) on the MWNTs / GCE modified by multiwalled carbon nanotubes Surface electrocatalytic oxidation behavior, while pH, scanning speed, temperature and other test conditions were also studied. The results showed that MWNTs / GCE electrode exhibited good electrocatalysis and electrocatalysis for both CC, HQ and RS. Under the condition of high concentration of HQ and RS, the oxidation peak current of CC was in the range of 0.05-7.00 mmol / L And the concentration showed a good linear relationship, the correlation coefficient R ~ 2 = 0.9989; modified electrode to achieve the actual wastewater three hydroquinone in the determination.
