全固态漆酚树脂儿茶酚化学传感器

All-Solid-State Urushiol Resins Catechol Sensor

研制了一种新型的以漆酚树脂为载体的全固态电位型化学传感器 ,用以测定儿茶酚类药物 ,主要是对其分子结构中的邻苯二酚基团有选择性的响应 其Nernst线性范围为 1.0× 10 -3 ～ 5 .0×10 -6mol·L-1,斜率为 30 .0 ,检测限为 2 0× 10 -6mol·L-1(30 3K ,pH6 .0 ) 此传感器响应迅速 ,重现性好 。

A new all solid state catechol sensor using urushiol resins as carrier is introduced This sensor has selective responsibility to o dihydroxybenzene group in the catechol which affords linear response in the range of 1.0×10 -3 ~5.0×10 -6 mol·L -1 with the detection lower limit of 2 0×10 -6 mol·L -1 and the slope 30.0(303K, pH6.0)and high responsibility,stability and reproducibility The result of detection is the same with pharmacopoeia
