Abstract：Amethodforthedeterminationoffiveelements，namelylead，cadmium，chromium，arsenic，andmercuryin inksfor foodcontactmaterialsandproducts byinductivelycoupled plasmaopticalemissionspectrometry （ICP-OES）was establishedaccording tothestandard GB4806.14-2023.Solvent-basedinks were pretreated bymicrowavedigestion，and an ICP-OES analyzer was used to determine the five heavy metal elements.The minimumdetection limits ofthe method were in the range of 0.011mg/kg to 0.528mg/kg ，the relative standard deviations were between 1.66% and 7.99% ，and the recoveries of the spiked sampleswere between 85.1% and 110.4% .Theresults show that this method is simple in sample processingwithhighefciencyanditsresultsareaccurateandreliable，whichissuitablefortheanalysisanddetectionof lead，cadmium，chromium，arsenic，and mercuryininks for food contact materialsand products.
