摘要：

An enzymeless sensor based on a multi-walled carbon nanotubes-dicetyl phosphate (MWCNT-DCP) film modified vitreous carbon electrode was developed for the determination of hypoxanthine. The MWCNT-DCP film modified electrode showed a remarkable enhancement effect on the oxidation peak current of hypoxanthine. Under the optimized conditions, the oxidation peak current is proportional to the concentration of hypoxanthine over the range from 5.0 x 10-(7) to 2.0 x 10(-4) mol L-1 with a detection limit (SIN = 3) of 2.0 x 10(-7) mol L-1. The MWCNT-DCP film modified electrode has been successfully used to detect hypoxanthine in fish samples.
