Sorption removal of Fe(CN)6 3− ion impurities from water and evaluation of water quality by the biotesting method

The sorption removal of Fe(CN)6 3− ion impurities from water was investigated. A specially synthesized magnesium-aluminum double hydroxide with the hydrotalcite-type structure was used as a sorbent. The biotesting method used for various test objects proved the efficiency of sorption removal of Fe(CN)6 3− from water.
