A novel method for the determination of acetaminophen was developed based on its inhibition effect on the luminol-H2O2-silver nanoparticle chemiluminescence system.Various factors influencing the chemiluminescence system were investigated and the possible mechanism was also studied.Under the optimum conditions,the linear range for the determination of acetaminophen is 2.0×10-8 to 1.0×10-4 mol/L with a detection limit of 4.0×10-9 mol/L.The relative standard deviation is 2.6% for 1.0×10-7 mol/L acetaminophen solution in nine repeated measurements.The method was successfully applied to the determination of acetaminophen in pharmaceutical.
