Recovery of lithium using H4Mn3.5Ti1.5O12/reduced graphene oxide/polyacrylamide composite hydrogel from brine by Ads-ESIX process
文献摘要：
Powdery Li+-imprinted manganese oxides adsorbent was widely used to the recovery of Li+,but there are some difficulties,such as poor stability in acid solution,inconvenience of operation and separation.In this work,a useful hydrogel composite based H4Mn3.5Ti1.5O12/reduced graphene oxide/polyacrylamide(HMTO-rGO/PAM)was fabricated by thermal initiation method with promising stable,conductive and selective properties.The resulting materials were characterized by field emission scanning electron microscope,infrared absorption spectrum,X-ray diffraction,X-ray photoelectron spectroscopy and elec-trochemical techniques.The recovery of Li+was investigated using HMTO-rGO/PAM from brine by a sep-arated two-stage sorption statically and electrically switched ion exchange desorption process.The adsorption capacity of 51.5 mgg-1 could be achieved with an initial Li+concentration of 200 mgL-1 in pH 10,at 45℃for 12 h.Li+ions could be quickly desorbed by cyclic voltammetry(CV)in pH 3,0.1 mol·L-1 HCl/NH4Cl accompanying the exchange of Li+and H+(NH4+)and the transfer of LMTO-rGO/PAM to HMTO-rGO/PAM.
