摘要
报导了一种测定淀粉的酶生物传感器法，它具有检测速度快、灵敏度高、操作简便、且样品需要量少等优点。酶生物传感器是由固定化的ＧＯＤ、ＧＡ酶膜和氧电极组成，测试的最佳条件为温度３０℃，ｐＨ＝４．４，０．２ｍｏｌ／Ｌ醋酸缓冲液，响应时间２ｍｉｎ。该法的精密度、准确度均良好，线性范围０．０５％～０．８％。
An enzyme biosensor method for stsrch is rePOrted in the paper. It is of simple, quick,sensitive. It is composed of GOD,GA membranes and oxygen electrode. The measurable optimal conditions are pH=4.4, 0.2 mol/L ammonium acetate buffer,temperature 30 ℃, respond time 2 min. The precision and accuracy are good. Linear range is 0.05% ～0.8%
