【摘要】 利用循环伏安法制备了聚对氨基苯磺酸修饰电极,研究了其对对苯二酚的电催化作用,并初步探索了其催化机理。将该电极用于对苯二酚的定量测定,发现其氧化峰电流与对苯二酚的浓度在1.0×10-6～8.0×10-5 mol/L范围内呈良好的线性关系,相关系数r=0.9894,检测限为5.0×10-7 mol/L。将该方法用于照相显影剂中对苯二酚的测定,结果满意。更多还原

【Abstract】 A polyp-aminobenzene salfonie acid modified electrode has been prepared,the electrochemical behavior of hydroquinone has been studied on the modified electrode.At the same time,The dectrocatslytical mechanism was also studied.The catalytic current of hydroquinone vs its concentration has a good linear relation in the range of 1.0×10-6～8.0×10-5 mol/L,with the correlation coefficient of 0.9894,Detection limit is 5.0×10-7 mol/L.The modified dectrode was applied to the determination of hydroquinone in photographic imaging agent with satisfactory results.更多还原
