摘要
采用电沉积法，研制了在低碳钢基体表面沉积Co—P非晶型合金的化学传感器，用来测定亚硝酸根含量，效果十分理想。其Nemst线性范围为1．0×10^-2～1．0×10^-6mol／L，斜率为47mV／dec，检测下限可达6．0×10^-7mol／L。此传感器响应迅速，选择性好，重现性好，使用寿命较长，稳定性好。
A new type of chemical sensor was prepared by deposition of Co-P non-crystal alloy on the surface of low carbon steel using electrodeposition method. The sensor was good for the determination of nitrite. It had high stability high reproducibility and long service life. Its Nemst response was in the range of 1.0×10^-2～1.0×10^-6mol/L with detection lower limit of 6.0 ×10^-7 mol/L and slope of 47 mV/dec.
