抄録
Spinel type manganese oxide shows a specific selectivity for lithium ions and is the most promising adsorbent for recovery of lithium from seawater. In order to develop a technology for lithium recovery from seawater, we carried out research works on development of spinel-type manganese-oxide adsorbent, granulation of powdered adsorbent, column adsorption and desortption, and bench-scale adsorption from seawater.<BR>The powdered adsorbent obtained by the acid treatment of (Li) [Li0.33Mn1.67] O4 showed the largest lithium uptake (above 20 mg/g) from seawater. The adsorbent was granulated with poly vinyl chloride as a binder. The granulated adsorbent maintained large adsorptive capacity for lithium and had a high lithium ion dif hisivity. The lithium adsorption by fluidized bed column, the lithium desorption with an acid, and the repetition of adsorption desorption cycle were investigated. On the basis of these studies, a fluidized-bed type adsorption bench was designed and constructed using a cone-shaped column. Li2CO3 powder (750 g) with a purity of 99.1% could be recovered from seawarer by the 7 time repetitions of adsorption desorption cycle. Several R/D theme have been proposed for future practical utilization of the recovery system.
