Electrokinetics couples with the adsorption of activated carbon-supported hydroxycarbonate green rust that enhances the removal of Sr cations from the stock solution in batch and column

Preparation of Porous Composite Phase Na Super Ionic Conductor Adsorbent by In Situ Process for Ultrafast and Efficient Strontium Adsorption from Wastewater

“…Among these purification methods, adsorption has attracted considerable scholarly attention owing to its low cost, simple operation, less susceptibility to secondary contamination, superior adsorption capacity, and selectivity for systems with low concentrations of the target ions [20,21]. Commercially available conventional adsorbents, such as zeolites [22], resins [23], activated carbon [24], and minerals [25],…”

Efficient adsorption of strontium by in situ electrochemical synthesis of monohydric phosphate intercalated layered double hydroxides

“…3,4 The most commonly used adsorbents for the treatment of LLRWs are zeolites, titanates, zirconium organic phosphonates, carbon-supported hydroxycarbonate green rust (GR-AC) and metal-organic frameworks (MOFs). [5][6][7][8] Layered double hydroxides (LDHs) are metal oxide adsorbents that can be used to adsorb pollutants such as heavy metals, radionuclides, and organic anions in wastewater. 9 The general chemical formula of LDHs is [M 2+ 1Àx M 3+ x (OH) 2 ] x+ [A nÀ ] x/n ÁyH 2 O, M 2+ and M 3+ represent divalent cations and trivalent cations, respectively, A nÀ represents the interlayer anion, and x represents the ratio of M 3+ to (M 2+ + M 3+ ), generally ranging from 0.2 to 0.5.…”
