Rapid　analysis　of　trace　amount　of　aromatic　amines　in　environmental　samples　and　daily　necessities　has　attracted　considerable　attentions　because　some　of　them　are　strongly　toxic　and　carcinogenic.　In　this　study,　fast　and　efficient　electrophoretic　separation　and　sensitive　determination　of　5　banned　aromatic　amines　were　explored　for　practical　analysis　using　disposable　plastic　microchips　combined　with　a　low-cost　laser-induced　fluorescence　detector.　The　effect　of　running　buffer　and　its　additive　was　systematically　investigated.　Under　the　selected　condition,　5　fluorescein　isothiocyanate　labeled　aromatic　amines　could　be　baseline　separated　within　90s　by　using　a　10　mmol/L　borate　buffer　containing　2%　(w/v)　hydroxypropyl　cellulose.　Calibration　curves　of　peak　areas　vs.　concentrations　were　linear　up　to　40　or　120　mu　mol/L　for　different　analytes　and　limits　of　detection　were　in　a　range　of　1-3　nmol/L.　Theoretical　plate　numbers　of　6.8-8.5　x　10(5)/m　were　readily　achieved.　The　method　exhibited　good　repeatability,　relative　standard　deviations　(n=5)　of　peak　areas　and　migration　times　were　no　more　than　4.6%　and　0.9%,　respectively.　The　established　method　was　successfully　applied　in　the　quantitative　analysis　of　these　banned　aromatic　amines　in　real　samples　of　waste　water　and　textile,　recoveries　of　added　standards　were　85-110%.　(C)　2013　Elsevier　B.V.　All　rights　reserved.
