ABSTRACT
Objective To establish a method for determining paraquat in the serum by ultraviolet spectrophotometry and present a quantitative index for paraquat poisoning salvage. Methods The sample was deproteinizated by 20% trichloracetic acid(TAC). 50 ?l microcell was used, the detection wavelength was 257 nm. Results The linearity was within 0.05~50 ?g/ml, r=0.999 9. The average recovery rates were 90.0%-102.4% and RSD=3.9%(n=4), the lowest detection limit was 0.01 ?g/ml. Conclusion The method is simple, rapid, precise and suitable for the determination of paraquat in the serum.
