| Abstract: | [Objective] A method for determining residue of nitrobenzene in fish was studied.[Method]The sample was extracted with acetone,cleaned-up with water vapour,and extracted by benzene.The mass spectrometer was operated for qualitative and quantitative analysis of nitrobenzene.[Result] The correlation coefficient of linear calibration curve was over 0.999 within the nitrobenzene concentration range 5-1 000 ng/ml.The recovery rate for nitrobenzene was between 75% and 110%.The relative standard deviation was betw... |
