Magnetic zeolite P with the spherical form was successfully synthesized from low-grade fly ash via hydrothermal synthesis method. These samples were characterized by XRD, XRF, FTIR, BET, VSM, SEM and TEM. The textural properties of magnetic zeolite P were further studied by N 2 adsorptiondesorption technique. In addition, the vibrating sample magnetometer study confirmed that the saturation magnetization is 11.99 emu·g −1 , indicating that magnetic zeolite P has sufficiently magnetic property to be attracted by a permanent magnet. Moreover, this facile approach to study saturation adsorption capacity and percentage removal of the magnetic zeolite P for Pb (II) and Cu (II) ions might expand the application of magnetic zeolite P in the adsorption of heavy metal ions, and it may be further extended to other magnetic zeolite materials.

“…18 These methods incur some drawback such as low-extraction rate, high cost, and environmental pollution that is why are being less practiced. [19][20][21][22] To obtain high-purity Ga products, chemical precipitation method was applied too, but the purity is poor. Ga(OH) 3 precipitation is easy to precipitate with other impurities due to its amorphous with a high-specific surface area.…”

Resin adsorption methods are widely used to recover gallium (Ga) from Bayer liquid. However, when the resin adsorbs Ga(III), a part of vanadium (V), magnesium (Mg), silicon (Si), calcium (Ca), and aluminum (Al) were coextracted with Ga and then was eluted together by using hydrochloric acid (HCl) solution. These impurities would affect the recovery of high-purity Ga by electrolysis. Ga-bearing acid eluted solution treatment followed by secondary adsorption was used to purify Ga(III) by a porous silica-based adsorbent tributyl phosphate (TBP)/SiO 2-P. The adsorption properties of Ga(III) by TBP/SiO 2-P from HCl were investigated. TBP/SiO 2-P exhibits significantly high selectivity toward Ga than other impurities with SF A/B is 3478 in 8 mol/L HCl solution. The adsorption capacity reaches 22.01 mg/g and adsorption equilibrium was obtained within 5 min. Moreover, Ga(III) is easy to be eluted by ultrapure water with a rate of 95.58%. The adsorption kinetics and isotherms of Ga fit well with the pseudo-first-order model and Langmuir adsorption model, respectively. TBP/SiO 2-P is an excellent material to recover Ga(III) from HCl solution effectively and efficiently. Moreover, this work provides a potential candidate for purifying Ga from Bayer liquor by the two-step method (purify and adsorb the desorption liquid containing Ga hydrochloride). Highlights • A silica-polymer based adsorbent TBP/SiO 2-P was prepared through a simple vacuum impregnation method and use to purify Ga from Bayer liquor by the two-step method. • A simple and efficient method for Ga purification was proposed with a high-adsorption capacity and short equilibrium time. • In the coexisting ions mixed solution, TBP/SiO 2-P has a high-selective toward Ga(III), Ultrapure water can effectively desorb Ga from adsorbent with the desorption rate of about 95.58%.
