摘要
应用多壁碳纳米管修饰电极测定邻苯二酚,研究了测定过程中酸度、干扰物质、线性范围等对测定的影响.结果发现,在pH值为2.0时,催化效果最好,在该修饰电极上,可以有效分开对苯二酚和邻苯二酚.测定线性范围为5.0×10-6g.ml-～ 2.0×10-4g.ml-.
In this paper, catechol is determinted by carbon-nanotube modified electrode. The pHvalue, disturbing material and linear range that influence the determination are studied. The best pH value is 2.0. A good linear range of catechol is between 5. 010^-6g. ml^- and 2.010^ -4g. ml^-.
