Abstract: 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.
