In this work, Li1.6Mn1.67O4 is successfully prepared by solid state reaction method and firstly prepared as adsorbent for geothermal fluid of Lumpur Sidoarjo. XRD shows the all samples are indexed as Li1.6Mn1.67O4 with spinel structure. The further increase of calcination temperature, diffraction peaks of Li1.6Mn1.67O4 are growing strong and sharp, implying an improved crystallinity and an increased grain size. SEM images of LMO adsorbent show irregular shape with particles size in the range of 15-52 μm. Li1.6Mn1.67O4 at 700 ºC has the highest capacity of lithium adsorption with capacity of 29.8 mg/g. It is attributed to the high crystalline of Li1.6Mn1.67O4 at 700 ºC compared with other samples. In addition, the higher calcining temperature will result in the increasing grain size and crystallinity that enhance the adsorption performance of the Li1.6Mn1.67O4 adsorbent.
