摘要
银粉废水中和渣样品用逆王水、高氯酸溶解,消解有机物,在10%盐酸介质中,于波长328.1nm处,测量溶液的银离子浓度,从而计算得出试样含银量。通过试验,溶液中共存杂质离子几乎不干扰测定,方法的相对标准偏差(RSD)小于3.11%,加标回收率在98%~102.8%之间,测定范围100~1000 g/t。
Silver powder wastewater neutralization of the sample with the inverse king of water, perchloric acid dissolved, digestion of organic matter in 10% hydrochloric acid medium, the wavelength of 328.1nm, the measured solution of silver ion concentration, which calculated the sample silver content. The relative standard deviation （RSD） of the method was less than 3.11%. The recoveries ranged from 98% to 102.8%. The determination range was 100- 1000 g/t.
