| Abstract: | Br-PADAP-OP coloured system is used to determine copper. The meassuring conditions are researched. Trioctylamine is used to entract and seperate from interference ions. The conditions of extracting and seperating from interference ions are studied. The recovery of synthetic sample is 100. 8%. The relative error of determining results for standard samples of aluminium alloy are less than -2. 2%. The relative standard deviation of analytical results for human hair are less than 4. 0%. |
