摘　　要：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。Two types of sensor for glycollic acid were prepared and studied, which consist of spinach and aster indicus as the biocatalyst respectively, and an oxygen electrode as base electrode. The linear range of response curve of spinach tissue-based electrode is 5.0× 10^(-6)-1.0× 10^(-4)mol/L,response time is 3 min, and life-time is 10 d. The linear range of the aster indicus tissue-based electrode is 2.0×10^(-6)-1.0×10^(-4)mol/L,response time is 3 min and life-time is 30 d. The two types of sensor are possessed of high selectivity to glycollic acid.
