| 中文摘要: |
| 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22 μg/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%。 |
| 英文摘要: |
| 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,including 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 detection 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%. |
