Abstract

Due to the low sensitivity of flame atomic absorption spectrometry for trace copper determination, dispersive liquid-liquid microextraction and slotted quartz tube were used to increase the instrument's detection power by about 102-fold. This high detection improvement was achieved by performing a comprehensive optimization study on the microextraction method and slotted quartz tube parameters.
