摘要
本文报道了铋在活性炭上的吸附行为和解吸附条件，发现铋在ｐＨＯ～１２内均可被活性炭吸附，吸附于活性炭上的铋可用５０％硝酸洗脱，由此而建立了一种活性炭富集水中超痕量铋的方法，结合示波极谱法可测定水中低至５ｎｇ／Ｌ水平的铋。
The adsorption behaviour of bismuth on activated carbon and its desorption method were studied. It was found that bismuth could be completely adsorbed by activated carbon in the pH 0-12, and the absorbed bismuth could be quantitatively desorbed with 50% nitric acid. A method for the preconcentration of ultratrace bismuth in water was established, and combined with oscillopolarography, bismuth as low as 5 ng/L in water could be determined.
