ICP-MS与ICP-OES测废水中铊的比对

The Comparison of Measuring Thallium in Wastewater between ICP-MS and ICP-OES

用ICP-MS和ICP-OES测量铊不同浓度的废水样品,ICP-OES未能检出低含量铊的样品,且铊含量在ppm级别时有较好的回收率。然而ICP-MS线性范围宽,测量效果在高中低浓度的样品中表现较好。

To measure the concentration of thallium in different wastewater samples by ICP-MS and ICP-OES, ICP-OES was not able to detect the low level thallium, and it had a better recovery rate when thallium concentration was in the ppm level. However, ICP-MS had a wide linear range, the test results showed good performance in the low, medium even high concentration of samples.
