The invention discloses a method for measuring the content of
arsenic in
edible oil by utilizing a super-
microwave digestion graphite furnace atomic absorption spectrometry. The method disclosed by the invention comprises the following steps: performing super-
microwave digestion on an
edible oil sample by adopting a transparent and stable
quartz tube, and measuring the content of the
arsenic in the
edible oil by utilizing the
graphite furnace atomic absorption spectrometry. According to the method, a super-
microwave technology is applied to measuring the trace
arsenic in the edible oil, the operation is safe and easy, the
digestion capacity is high, the edible oil samples can be simply and efficiently digested, the target
analyte loss and
pollution caused by the transfer process can be effectively eliminated,
potassium borohydride and other substances with high
toxicity are not needed, and the
graphite furnace atomic absorption spectrometry is further combined to be applied to measuring the trace arsenic in the edible oil. According to the method disclosed by the invention, the
linearity range ranges from 0 to 40ng / mL, the quantification limit is 0.033mg / kg, and the
recovery rate is 86.8-101.4 percent. The operation is easy, accurate, rapid and sensitive, the content of the arsenic in the edible
oil can be accurately measured, and the body health of consumers can be effectively guaranteed.
