A new method was developed for determination of thallium in waste water with the inductively coupled plasma atomic emission spectrometry (ICP-AES)by studying the optimum analytical conditions,inclu-ding the interference effect of wavelength,medium and its acidity,coexisting elements.The linear range was from 0 mg /L to 5.00 mg /L with 0.999 9 of the linear correlation coefficient of the standard curve.The limit of detec-tion was 22 μg /L,the relative standard deviation of four wastewater samples was from 0.2% to 0.8%,and the recovery of the spiked water samples was from 98.0% to 100%.
