摘要
扫速为100 mV/s时,在不同的条件下于一定浓度的天冬氨酸聚合底液中制作玻碳修饰电极,分别利用肾上腺素(EP)、去甲肾上腺素(NE)和多巴胺(DA)作为探针进行伏安测定,探讨了聚L-天冬氨酸修饰玻碳电极(PL-ASP/GCE)的最佳制备条件,实验表明,在最佳制备条件下PL-ASP/GCE的稳定性和重现性良好。
The voltammetric behaviors of epinephrine(EP),norepinephrine(NE) and dopamine(DA) with the 100 mV/s of the scanning rate was determined on the poly(L-aspartic acid) modified electrode which was made in the solution of L-aspartic acid,respectively,using EP,NE and DA as probe.The best preparation conditions of the poly(L-aspartic acid) modified electrode was explored.The results showed that the modified electrode showed better stability and repeatability with satisfactory value under the optimum preparation conditions.
