　　Azobisisobutyronitrile is a compound often used as a radical initiator in polyacrylonitrile.The amount of AIBN must be strictly controlled; otherwise the product quality will be affected.And AIBN is highly toxic.Therefore, the detection of AIBN residue in polyacrylonitrile solution is necessary.AIBN has traditionally been detected using Spectrophotometer.However, matrix interference of Spectrophotometry method is too high.
