It is reported in this paper that diphenylcarbazone reacts with Hg in pH 2.2 in the presence of Tween─60 to form a purple complex with its absorption maximum at 486 nm. The existence of chloride will depress the absorption of the complex. The negative absorption will be proportional to the consistence of chloride.

摘要﹞ 在pH为2.2的酸性介质中，在吐温－60溶液的存在下，Hg与二苯卡巴形成紫色的配合物，其最大吸收波长为486 nm，氯离子的存在可使原紫色配合物吸光度降低，其负吸光度与氯离子浓度成正比。
