中文摘要 | 4-aminophenol (4-ap), paracetamol (prct), norepinephrine (ne), and dopamine (da) (all somewhat hydrophobic compounds) were hplc electrochemically detected while the signals from uric acid (ua) and ascorbic acid (aa) (both hydrophilic compounds at the ph studied) were minimized, taking advantage of the permselectivity of the self-assembled n-alkanethiol monolayer (c-10-sam)-modified au electrodes based on solute polarity, the effects of various factors, such as the chain length of the n-alkanethiol modifier, modifying time, and ph value, on the permeability of c-10-sam coatings were examined, the calibration curves, linear response ranges, detection limits, and reproducibilities of the ec detector for 4-ap, prct, ne, and da were obtained, the result shows that the ec detector can be applied in the chromatographic detection of 4-ap, prct, ne, and da in urine, effectively removing the influence of ua and aa in high concentrations existing in biological samples. as a result, a great improvement in the selectivity of ec detectors has been achieved by using au electrodes coated with neutral n-alkanethiol monolayer. |
