Lumpur Sidoarjo is one of geothermal fluid types which has a great potential as source of lithium. Adsorption method with Lithium Manganese Oxide (LiMn{sub 2}O{sub 4}) as an adsorbent has been chosen for lithium recovery process due to low production cost and environmental friendly. LiMn{sub 2}O{sub 4} was synthesized by hydrothermal method at 200 °C for 24 hrs, 48 hrs, and 72 hrs. As prepared LiMn{sub 2}O{sub 4} powder is treated by acid treatment with 0.5 M HCl solution for 24 hrs. XRD test result reveals that all of as-prepared samples are indexed as spinel structure of LiMn{sub 2}O{sub 4} (JCPDS card no 35-0782) with no impurity peaks detected. SEM images show that LiMn{sub 2}O{sub 4} has nanoparticles morphology with particle size around 25 nm. The highest adsorption efficiency of adsorbent is obtained by sample hydrothermal for 72 hrs with 42.76%.
