Retention Behavior and Dynamic Sorption of Strontium Ions from Aqueous Media Using Fabricated Inorganic Sorbent

Sorption of Sr(II) from aqueous solutions has been studied using fabricated lithium magnesium boron silicate (LMBS) sorbent. LMBS sorbent has been fabricated by the co-precipitation technique and characterized using different analytical tools like ATR, SEM, TGA, DTA, and XRD. The sorption studies applied on Sr(II) include the effect of shaking time, ionic strength, pH, and temperature. The sorption of Sr(II) is dependent on pH and ionic strength. Reaction kinetics follows the pseudo-2nd-order model, and thermodynamics are endothermic and spontaneous. The saturation capacity of sorbent calcined at temperatures 50, 200, 400, and 600 degrees C has been found to be 144.1, 134.5, 130.3, and 113.0 mg g(-1), respectively. Desorption studies have revealed that HCl is the optimum eluent for full recovery of Sr(II) ions (about 96.8%). Finally, according to column data, Sr(II) can be loaded and recovered from aqueous solutions using different concentrations of HCl eluent. The investigation has proved that LMBS is a suitable sorbent material for the recovery of Sr(II) from liquid waste.
