Enhanced removal of dissolved metal ions in radioactive effluents by flocculation

An isotope dilution–precipitation process for removing radioactive cesium from wastewater

“…Some researchers however, have forgone the column application and used the metal ferrocyanide as a direct precipitant/absorber of cesium. The precipitant has then been removed by filtration [12], centrifugation [13], flocculation [14], or flotation [15].…”

Effect of adsorbents and chemical treatments on the removal of strontium from aqueous solutions

“…During the last decades, researchers have put numerous efforts to develop suitable processes for better separation of radioactive ions from wastewater. Currently, there are many physico-chemical processes for the removal of these ions from waste streams such as: chemical precipitation and flocculation [2], phosphate precipitation [3], Cu or Ni ferrocyanide precipitation [4], ion exchange [5][6][7], membrane process [8][9][10], immobilization method [11] and adsorption [12]. Among these, adsorption is one of the most effective and economic methods.…”

Efficient Removal of Cobalt(II) and Strontium(II) Metals from Water using Ethylene Diamine Tetra‐acetic Acid Functionalized Graphene Oxide

“…These applications produce radioactive wastes in hospitals and research laboratories . Many methods have been established for removal of radioactive wastes including: chemical precipitation, ion exchange, membrane process, adsorption, etc. The adsorption method has many advantages such as: greater accessibility, low cost, simple operation, effective removal of radioactive material from aqueous solution etc.…”
