Abstract: The added amount,particle size,type of bentonite as an adsorbent for adsorpingheavy metallic ions in the battery solution were studied.And temperature influence of ad-sorptive capacity was also studied.Results show that the bentonite is a good adsorbent forheavy metallic ions in the battery solution,The replacement of flour and starch with ben-tonite in making paste layer of battery will not only save grain and reduce the cost, but alsoimprove the properties of battery to meet the national standard(GB 7112-86).

Key words: bentonite, montmorillonite, battery solution, heavy metallic ion, adsorption
