    • 摘要: 溶液阴极辉光放电-原子发射光谱法是近年来兴起的一种新型水体金属离子检测技术,它具有快速,在线和低成本检测的显著特点.以工业注射泵实现溶液阴极辉光放电激发源的流动注射进样,再以窄带滤光片分别提取Na,K,Ca,Li,Sr和Cs金属元素发射光谱信号,最后由光电倍增管和皮安表接收光谱信息光谱信号,实现了水质金属元素的检测.实验分析了注射容量分别为100和166μL对1 mg·L-1的Na元素产生的信号强度的影响,研究发现其信号强度的相对标准偏差(RSD)分别为4.64% 和1.95%,说明两种注射量稳定性都较好.为了获得更好的分析性能,实验分析了直流放电电压,狭缝的宽度以及光电倍增管供压等参数对信号强度的影响.实验结果表明,在直流放电电压为1000 V,狭缝宽度为70μm和光电倍增管供压为-800 V时获得了较高的信背比.采用此装置在流动注射模式下,测得了Na,K,Ca,Li,Sr和Cs六种金属元素检出限,分别为2.78,4.23,589,9.45,981和83.6μg·L-1.实验最后对混合溶液标定物质中的Na和K元素进行了定量分析测量,测量的误差分别为7.5% 和6.67%,精密度分别为1.24% 和0.89%,研究结果表明基于滤光片提取光谱的流动注射分析-溶液阴极辉光放电-原子发射光谱方法具有较高的检测准确度.

Methods Combined flow injection analysis (FIA) with new catalytic spectrophotometry, a new method for determination of iodine with no need of arsenic reagents was developed by the author. An ammonium persulfate digestion-flow injection catalytic spectrophotometry for determination of iodine in urine was established. Standard serial solutions and urine samples were all digested by ammonium persulfate before testing. The standard curve linearity in the range of 0-1200μg/L, detection limit,precision and accuracy in determining urinary iodine were tested. Results A good calibration relation of C=aA2+bA+d (C:iodine concentration,A:measuring absorbance peak area from FIA) of the newly developed method existed in the range of 0 - 1200 μg/L. The linear correlative coefficient was 0.9998. The FIA analysis speed was 60 samples per hour. The detection limit for urinary iodine was 7.1μg/L. Precision:The intra-assay coefficients of variation (CV) were 0.3% - 3.0% (n = 6) when measuring 9 urine samples with iodine concentration of 61.8-806.8μg/L;the intra-assay CV were 0.2%-1.7%(n=6) when measuring 5 urinary iodine national standard materials with iodine concentration of 76.9 - 883.0 μg/L; the inter-assay CV were 1.0% - 1.2% when measuring 6 batches of 3 urinary iodine national standard materials with iodine concentration of 76.9 - 232.0 μg/L. Accuracy:The average recovery rate was 98.3% with a range of 91.2% - 104.6% when measuring 20 urine samples with iodine concentration ranged from 18.9 to 807.1 μg/L. The test results of 5 urinary iodine national standard materials were all within the given value range and the relative deviations ranges were-2.9%-0.7%. No significant difference was found between the results of the 48 urine samples determined by the current standard method (WS/T 107.1-2016) and the new method (t=0.029, P>0.05). Conclusions The new method has a wide standard curve range, high sensitivity, good precision and accuracy, and is simple and easy to operate, with automatic sampling, rapid analysis, and no need for toxic arsenic reagent which is difficult to obtain and can pollute the environment. The method is suitable for widely application and can be used as a reliable technical method for urinary iodine detection.
