本文研究了在液流连续体系中还原汞,避免了用SnCl_2易生成偏锡酸沉淀的缺点,因此可用来测定和连续监测环境水中的汞,在0.5—6ppb范围内有良好的线性关系,检出限为0.1ppb.
In this paper, we studied the reduction of mercury in the continuous flow system to avoid the disadvantage of easy precipitation of metastannic acid with SnCl 2. Therefore, it can be used to measure and continuously monitor the mercury in environmental water with a good linear relationship in the range of 0.5-6ppb. The limit is 0.1 ppb.
