Composite Ion Exchangers Based on KU-23 and KM-2P Cation Exchangers and Nickel(III) Hydroxide and Their Use for Purification of Nickel Sulfate Solutions To Remove Cobalt(II) Impurity

A method of preparing composite ion exchangers based on macroporous cation exchangers and nickel(III) hydroxide was developed, and their suitability for deep purification of nickel(II) sulfate solutions to remove small amounts of cobalt(II) was demonstrated.     

Acid-Base Properties and Structural Features of Composite Ion Exchangers Based on KU-23 and KM-2p Cation Exchangers and Hydrated Zirconium Oxide

A method for introduction of hydrated zirconium oxide into macroporous cation exchangers KU-23 and KM-2p and the acid-base properties and structural features of the composite ion exchangers are described.     

Purification of Ammonium Molybdate and Tungstate Aqueous Solutions To Remove Phosphate,Arsenate, and Silicate Anions with a Composite Sorbent Based on KU-23 and KM-2p Cation Exchangers

Selectivity sorption of phosphate, arsenate, and silicate anionic impurities from concentrated aqueous solutions of ammonium molybdate and tungstate by a composite sorbent consisting of macroporous KU-23 (or KM-2p) cation exchanger and hydrated zirconium oxide was studied.
