The invention relates to the technical field of element detection, in particular to a method for detecting harmful elements in tattooing ink, which specifically comprises the following steps: S1, sample pretreatment: weighing a tattooing ink sample, adding
nitric acid for heating
digestion, S2, acid removal and constant volume: heating until complete
digestion, continuing heating for acid removal, cooling, transferring into a
volumetric flask for constant volume to obtain a to-be-detected solution, and detecting the content of harmful elements in the tattooing ink. S3, instrument detection: uniformly mixing the to-be-detected liquid, and carrying out multi-element simultaneous determination on the to-be-detected liquid by adopting an
inductively coupled plasma emission spectrometer, and S4, result analysis: quantitatively analyzing the contents of
arsenic,
cadmium,
cobalt,
copper, mercury,
nickel, lead,
antimony and
zinc elements in the
tattoo ink sample according to detection signals. The method for detecting the harmful elements in the tattooing ink not only has high sensitivity and accuracy, but also has high efficiency,
high flux, strong pertinence and wide applicability, and has important
social benefits.
