Extractability of Copper(II) and Zinc(II) with Crown Ethers as Picrates

Copper(II) extraction with crown ethers as picrates is better than zinc(II) extraction, but the difference is smaller than in extraction with -diketones.

Extractive fluorimetric determination of ultratraces of lead with 18-crown-6 and eosin.

The developed spectrofluorimetric method effectively determines ultratraces of lead in tap water, with good agreement with the more common extractive atomic-absorption method using ammonium tetramethylenedithiocarbamate.

The Solvent Extraction of Silver and Thallium(I) Picrates by Crown Ethers

Crown ethers play a crucial role in extracting silver and thallium(I) picrates from benzene solutions, with their stability influenced by factors such as cation size, crown ether flexibility, and donor oxygen atom basicity.

The selective extraction and spectrophotometric determination of copper and silver by the use of a thiocrown compound 1,4,8,11-tetrathiacyclotetradecane.

The proposed selective extraction and spectrophotometric determination method for copper and silver, using 1,4,8,11-tetrathiacyclotetradecane, is highly selective and sensitive, with BCG providing the highest sensitivity among three anions.
