过滤法:其作用是滤出汞中的灰尘杂物和不溶于汞的金属氧化物,其方法是在过滤用的漏斗中,放一张折成圆锥形的滤纸,在滤纸顶端用大头针扎一细孔,使汞沿滤纸顶端的细孔流出。酸洗法:用此法可清除汞的金属污物。装置如下图所示:酸式滴定管(1)的上端是过滤
Filtration method: Its function is to filter out the dust and impurities in the mercury and insoluble metal oxides. The method is to put a filter paper folded into a conical filter in the funnel for filtration, and use a pin at the top of the filter paper. The pores allow mercury to flow out through the pores at the top of the filter paper. Pickling method: This method removes metal contaminants from mercury. The device is shown in the figure below: The upper end of the acid burette (1) is filtered
