摘要：
We report on a carbon paste electrode that was modified with a binuclear manganese(II) complex by the drop-coating method. A study on the mechanism of the electro-oxidation of tryptophan (Trp) at this electrode indicated that it enables Trp to be determined with good sensitivity and selectivity. Second-order derivative linear sweep voltammetry at pH 4. 1 revealed that a sensitive anodic peak appears at 812 mV (vs. SCE) whose current is proportional to the concentration of Trp in the concentration range from 0. 1 to 1. 0 μmol L -1 and 1. 0 to 8...
