Abstract: | A new spectrophotometric method for the determination of traces of copper has been developed. The method is based on the formation of a stable 1:2 complex of copper(II) and 1-pyrrolidinecarbodithioate and the isolation of this complex by extraction into chloroform. The absorbance is measured at either 269 nm or 435 nm. The detection limit is 0.03 mug, of copper per ml for absorbance measurements at 435 nm. |
