Abstract:
A method using Donnan dialysis for the preconcentration of some transition and rare-earth elements is described. Enrichment factors of about 20 are obtained in 1 hr. Calibration curves that are linear over 2 orders of magnitude are obtained with a relative precision of about 3% when Co(II) is used as an internal standard. The effect of aluminium in the receiver electrolyte on the interference caused by phosphate in the sample solution is discussed.

Masking and Demasking Agents
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on the metal...
