Potassium iron(III)hexacyanoferrate(II) supported on poly metylmethacrylate has been synthesized and investigated for the
strontium(II) removal from HNO3 and HCl solutions. The ion exchange material characterized by different techniques and found to be stable in 1.0–4.0 M HNO3 solutions, has been used to elaborate different parameters related to ion exchange and sorption processes involved. The data
collected suggested its use to undertake removal of Sr(II) from more acidic active waste solutions. Thus the material synthesized
had been adjudged to present better chances of application for Sr(II) removal as compared to other such materials.
