Lithium Recovery From Shale Gas Produced Water Using H2TiO3

This study aims to recover lithium ion in shale gas produced water which was synthesized in laboratory referring to composition of produced water of Marcellus shale area.The adsorbent used for recovering lithium in produced water was H2TiO3 which was synthesized with Li2CO3 and TiO2.The lithium adsorptive capacity was observed with changing pH of produced water and using NaHCO3 as buffer to fix the pH of produced water.Without using buffer, the adsorptive capacity was very low and the adsorptive capacity increased with increase in pH of produced water.By adding buffer, the adsorptive capacity increased to maximum adsorptive capacity of 23.6 mg/g.It is, however, lower than the theoretical maximum capacity due to high TDS concentration in the produced water.
