将半封闭混酸消化法与冷原子荧光法并用,对鱼体肌肉组织在95~140℃下进行消化并测定其总汞含量.实验结果检验表明,该方法精确度高,对于鱼汞国际标准样品(TORT-2,DORM-2)测定结果表明,实测结果与推荐值间的误差小于1.13%,是快速、准确地测定鱼体中总汞的理想方法.同时,此方法也适用于其它生物样品或沉积物和土壤中总汞的测定. |

By using half-closed, mixture acid and CVAFS, fish tissue had been digested at 95 - 140"C and its total mercury content was determined. The results has shown that this method has high precision, is easy to operate, and its error between the results of the determination and certified values is below 1.13% for fish reference material (TORT-2, DORM-2), and therefore is a satisfied method to determine total mercury in fish tissue accurately and rapidly. This method may be used to determine total mercury in other biological samples or sediments and soils. |
