| Reliable and simple flow-injection chelatometric titration techniques for determination of copper, nickel, lead
ions with conductometric detection have been proposed. A possibility of separate titration of these ions in mixture
(1:1 mole ratio) has been shown. The concentration determination range is (0.006-0.6) mg/L at injection volume 200
?L. The relative error does not exceed 10-20%. |
