A spectrophotometric method has been established to determine main chemical component acetaminophen in tablets of paracetamol. The results showed that a good linear relationship between the acetaminophen content and absorbance( A) was found in the range of 0. 04~8. 00 mg·L-1. The linear equation was A=0. 1210c+0. 0261 with a correlation coefficient of 0. 9968. The appar-ent molar absorption coefficient,recoveries and RSD were 1. 8×104 L·mol-1·cm-1,100. 2%and 1. 51%,respectively. The method is simple,convenient,fast and has been successfully applied to the determination of acetaminophen in paracetamol tablets.
