摘要
在pH1．5～2．0酸性溶液中，2．3－二氨基萘选择性地与四份硒离子反应，生成4，5－苯并基硒脑绿色荧光物质，用环已烷萃取，其荧光强度与Se4+的含量成正比，可定量测定硒的含量。
The trace Selenium could be determined in the medium of pH 1.5～2.0. An aqueous solution of the complex formed between selenium and 2, 3-diaminonaphalene (DAN) produces fluorescence emission produces fluorescence emission The content of selenium in water used to make Xiangquan wine has been determined by using the methodwith satisfactory results.
