A　fast　and　simple　method　to　allow　routine　analysis　of　waste　phosphors　was　developed　and　fully　validated.　Pb,　Hg　in　waste　fluorescent　lamps　phosphors　(WFP)　and　Pb,　Cd　in　waste　CRT　phosphors　(WCP)　were　quantified　by　inductively　coupled　plasma　atomic　emission　spectrometry　(ICP-OES).　Analytical　conditions,　including　choice　of　analytical　spectral　lines,　sample　dissolution　methods　and　many　other　standards,　were　studied.　Wavelengths　of　220.353,　228.802,　and　184.886　nm　were　selected　as　analytical　lines　for　determination　of　Pb,　Cd,　and　Hg　respectively.　Studies　showed　that,　Nitric　acid　could　be　used　for　dissolving　Cd　and　Hg,　and　alkali　fusion　method　for　Pb.　Detection　limits　of　Pb,　Cd,　and　Hg　found　were　1.8,　0.3　and　3mg/kg　respectively.　The　proposed　method　was　used　in　determination　of　target　elements　in　waste　rare　earth　phosphors,　giving　values　of　recovery　in　the　ranges　of　96.5%-104%,　98.5%-105%　for　Pb,　Hg　in　WFP,　and　98%-104.5%,　98%-104.5%　for　Pb,　Cd　in　WCP　respectively,　and　values　of　RSD　less　than　8%.　Also,　influences　by　dilution　factor,　coexisting　elements　and　HNO3　Concentration　etc.　were　discussed　in　the　paper.　©　2016　Trans　Tech　Publications,　Switzerland.
