When the sample contains functional groups such as hydroxyl and amino which are connected with a benzene ring, less exchanging reagent containing deuterated active hydrogen is added in a sample preparation process so as to avoid interferences on the functional groups; a used additive is a small organic molecule such as heavy water or deuterated methanol and ethanol; the adding amount is small and the pollution to the environment is small; an existing standard method is slightly changed, and the detection method is easy to popularize and implement, convenient to operate and low in cost.
