In this study, an in situ electrochemical modulation method based on ultramicro interdigitated array electrode (UIAE) sensor chip was developed for the detection of ammonia nitrogen (NH3-N) neutral aqueous solutions. One comb UIAE used as working both modulating and sensing functions, while other counter electrode. Utilizing its enhanced mass transfer proximity effects, feasibility solution environment near to generate response NH3-N investigated using methods. The proposed enhances concentration hydroxide ions active chloride local chip. These reactive species play a key role improving sensor’s electrocatalytic oxidation capability toward nitrogen, facilitating sensitive environments. A linear relationship displayed, ranging from 0.15–2.0 mg/L (as nitrogen) with sensitivity 3.7936 µA·L·mg−1 (0.0664 µA µM−1 mm−2), which 2.45 times that strong alkaline conditions without modulation. Additionally, relative standard deviation measurement remained below 2.9% over five days repeated experiments, indicating excellent stability.
