We　report　a　simple　and　highly　sensitive　method　for　the　simultaneous　detection　of　trace　zinc　dimethyldithiocarbamate　and　zinc　ethylenebisdithiocarbamate　by　capillary　electrophoresis　with　inductively　coupled　plasma　mass　spectrometry.　Zinc　dimethyldithiocarbamate　and　zinc　ethylenebisdithiocarbamate　were　chelated　with　trans-1,2-diaminocyclohexane-N,N,N′,N′-tetraacetic　acid　to　form　a　macromolecule　complex.　Then,　these　two　compounds　were　separated　by　α-cyclodextrin-modified　capillary　electrophoresis　within　12 min　at　a　separation　voltage　of　15 kV　and　measured　by　inductively　coupled　plasma　mass　spectrometry.　The　developed　method　is　sensitive　with　detection　limit　of　1.9　and　3.0 ng　Zn/mL　for　zinc　dimethyldithiocarbamate　and　zinc　ethylenebisdithiocarbamate,　respectively.　By　means　of　ultrasound-assisted　extraction　methods,　zinc　dimethyldithiocarbamate　and　zinc　ethylenebisdithiocarbamate　spiked　into　cabbage　leaves　were　successfully　extracted　and　determined　with　a　relative　standard　deviation　(n = 5) ≤ 6%　and　a　recovery　of　95–107%.　©　2017　WILEY-VCH　Verlag　GmbH　&　Co.　KGaA,　Weinheim
