The purpose of this paper is to develop high efficient lithium absorbent of manganese dioxide by mechanochemical treatment, using the same ball mill processing as the method applied to magnesium in the previous work. And the following interesting results are obtained.
1) Both the results of specific surface measurement by gas absorption method and the observation by SEM indicate that the size of primary particle of manganese dioxide powder is not changed and kept almost constant within the experimental condition of 0 to 48 hrs by ball mill handling.
2) The optimum ball mill handling time is pointed out to exist at 24 hrs, at which the maximum lithium adsorption of 10.79 mg lithium ion per 1 g of manganese dioxide was observed.
3) The maximum lithium adsorption quantity mentioned above is pointed out to be about 1.8 times of value on sample with 0 hrs handling, and it is more than twice of the case of magnesium oxide in the previous paper.
4) Above results, from 1) to 3), indicate that high efficient lithium adsorbent of manganese dioxide can be prepared by ball mill handling. described in this paper
