【摘要】 研究了在ｐＨ９．２５～１１．０的缓冲溶液中，在溴化十六烷基三甲铵（ＣＴＭＡＢ）存在下，Ｂｉ（Ⅲ）与邻氯苯基荧光酮（ｏ－ＣＰＦ）生成的紫红色络合物，其最大吸收波长为５７０ｎｍ，摩尔吸光系数为１．１２×１０￣５，Ｂｉ：ｏ－ＣＰＦ＝１：３，铋量在０～３０μｇ／２５ｍｌ范围内符合比尔定律，用于测定钨矿中的铋，结果满意。更多还原

【Abstract】 In this paper, spectrophotometric determination of bismuth with o-chlorophenylfluorone and cetyltrimethylammonium bromide is described.The molar absorptivity of the complex is 1.12×10￣5 L·mol￣(-1)·cm￣(-1) at 570nmBeer’s law is obeyed in the range of 0-30μg/25ml for bismuth It has been to determine bismuth un trngsten ore with更多还原
