Measuring method for quickly measuring contents of heavy metals in tobacco by using microwave digestion/ICP-MS method

The invention discloses a measuring method for quickly measuring the contents of heavy metals in tobacco by using a microwave digestion / ICP-MS (Inductively Coupled Plasma Mass Spectrometry) method. According to the measuring method, a microwave digestion pretreatment method is adopted, an ICP-MS is adopted to measure the contents of arsenic, plumbum, cadmium, chromium, copper, zinc, nickel and mercury elements in a digestion liquid, 75As, 208Pb, 111Cd, 53Cr, 63Cu, 66Zn, 60Ni and 202Hg are selected as mass numbers of the to-be-measured elements to reduce mass spectrum interference, and an internal standard element Rh is added in an off-line manner to inhibit the matrix effect. For to-be-measured ions with a certain mass-to-charge ratio, mass spectrum signal response is directly proportional to the number of ions entering the ICP-MS, the concentration of the elements in a sample is measured by measuring the number of mass spectrum signals, and the contents of the elements are calculated by a standard curve method.
