Azodicarbonamide(ADC),which has been abundantly used in the creation offoamed plastics as a blowing and foaming agent,has attracted more and more attention in recent years due to the health risks associated with its *** is actually on the REACH(Registration,Evaluation,Authorization and Restriction of Chemicals)regulation Candidate List of Substances of Very High Concern,and the residual content in products needs to be confirmed by the end users according to ***,the determination and monitoring of ADC in plastic products is necessary and crucial not only for the growth of ADC global market but also for the health of the *** this work,a quantitative method for ADC in insulation layers of cables was developed by using optimized total dissolution methodology(TDM)for sample preparation followed by HPLC under HILIC conditions with UV absorbance *** linear range of this method was 6–600μg·g^(-1) ,and the limit of detection(LOD)and limit of quantitation(LOQ)were 0.94 and 3.1μg·g^(-1) in solution,*** method has good recovery and precision,and is easy to *** meets the needs of the industry and is conducive to the growth of ADC global *** method is expected to be applicable to ADC quantitation in other polyolefin products.
