【摘要】 本文建立了痕量蒽、的同时磁场效应（ＭＦＥ）共振同步荧光分析方法。该法能有效地抑制同步扫描过程中散射光的波动而使在低试样浓度下测定蒽、的灵敏度提高。蒽和的检测限分别为０．１４和０．０２７ｎｇ／ｍｌ。相对标准偏差不大于６％。更多还原

【Abstract】 A magnetic field effect(MFE) resonant synchronous spectrofluorometric method for simultaneous determination of trace anthracene and perylene is described.In this method the undulation of scattering light is suppressed effectiviely,and thus the sensitivity is enhanced.The detection limits of anthracene and perylene are 0.14 and 0.027ng/ml respectively.The relative standard deviations are less than 6%.更多还原
