摘要:

An ultraviolet spectrophotometric method for the determination of selenium has been developed using ammonium 1-pyrrolidinecarbo-dithioate. The selenium(IV)-1-pyrrolidinecarbodithioate complex is extracted with chloroform and the absorbance of the extract measured at 303 mμ. Conformity to Beer's law was found for 0.5 to 9 ppm of selenium.
