This　paper　proposes　a　new　adaptive　analysis　method　for　ICP-AES,　which　can　handle　background　and　spectral　overlap　interferences.　It　is　different　from　the　traditional　method　in　that　the　component　concentration　values　of　a　sample　can　be　estimated　directly　by　adaptive　filtering　and　the　selection　of　background　references　is　independent　of　spectra.　The　power　of　the　new　method　is　illustrated　with　simulated　and　real　spectra.
