在测定血汞、尿汞的实际工作中,我们发现采用水冷循回硫酸分解试样测定血汞,操作不便;用酸性氯化亚锡和碱性氯化亚锡还原法测定尿汞,样品处理时间长,试剂空白高,不适于痕量汞测定。而采用低温微波溶样可弥补上述不足之处,用样量少,样品可在短时间内测定完毕,方法...
In the determination of blood mercury, mercury mercury in the actual work, we found that the use of water-cooled sulfuric acid decomposition of mercury samples for the determination of blood mercury, inconvenient to operate; acid stannous chloride and alkaline stannous chloride reduction method for the determination of urine mercury, sample processing A long time, reagent blank high, not suitable for trace mercury determination. The use of low-temperature microwave sample preparation can make up for these deficiencies, with less sample, the sample can be measured in a short time is completed, the method ...
