分别以菠菜和马兰叶为生物催化材料,将其叶浆组织与氧电极相结合,首次制成乙醇酸电极。本文研究了这两种电极的响应性能。菠菜组织电极线性范围为5.0×10~(-6)～1.0×10~(-4)mol/L;响应时间为3min,寿命为10天。马兰组织电极线性范围为2.0×10~(-6)～1.0×10~(-4)mol/L;响应时间为3min,寿命至少30天。这两种电极对底物乙醇酸钠皆有良好的选择性。 Spinach and Malan leaves were used as biocatalysis materials, respectively. The leaf tissue was combined with oxygen electrode to make glycolic acid electrode for the first time. This paper studies the response of these two electrodes. The linear range of spinach tissue electrode was 5.0 × 10 -6 ~ 1.0 × 10 -4 mol / L, the response time was 3 min, and the life span was 10 days. The linear range of Malan tissue was 2.0 × 10 -6 -6.0 × 10 -4 mol / L, the response time was 3 min and the life expectancy was at least 30 days. Both electrodes have good selectivity for the substrate sodium glycolate.
