摘要
采用电感耦合等离子体原子发射光谱仪(ICP-AES)测定废水中铊,并对测定波长、介质及其酸度、共存元素干扰等因素进行分析和条件优化,使该方法在0 mg/L^5.00 mg/L范围内线性良好,相关系数为0.999 9。方法检出限为22μg/L,该方法对铊标准样品测定的结果在保证值范围内,4份废水样7次测定结果的RSD为0.2%~0.8%,实际废水样品的加标回收率为98.0%~100%。
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%.
