摘要

The construction and characterization of a flow-through polarographic detector for catalyzing the electroreduction of N-nitrosodiethanolamine (NDELA), is discussed. The flow-through cell is equipped with a gold wire electrode (a thin mercury film deposited on a gold substance). The response is evaluated with respect to substance diameter, length, concentration of modifying film, operating potential, supporting electrolyte and pH, and flow rate in the DC mode. The system allows the determination of N-nitrosodiethanolamine in rabbit biological fluids with relatively inexpensive equipment.
