摘　　要：运用全化学分析、X射线衍射分析、红外光谱分析、差热分析和等离子质谱等分析方法,对邯郸地区的6个膨润土样品的矿物成分、化学成分、理化性能和微量元素进行了分析。结果显示,邯郸地区的膨润土为钙基膨润土,通过人工钠化转化为钠基膨润土后,物化性能优良。邯郸膨润土中富含多种有益微量元素,而害微量元素如Cd、Pb、As、Hg和Cr等的含量却低于国家规定的标准。综合分析表明,邯郸膨润土可以满足作为矿物饲料添加剂的要求。s:Mineral constitutes, chemical compositions, physical-chemical properties and microelement content of 6 Bentonite samples of Handan were studied by means of chemical analysis, XRD, IR, DTA, ICP-MS and so on. It is shown that Handan Bentonite belongs to Ca-base type and it is easily being transferred to Na-base type which has much better physical-chemical properties. Handan Bentonite is rich in many kinds of beneficialmicroelements for animals whereas the content of noxious microelements such as Cd, Pb, As, Hg, Cr and so on is much less than the level that national standard permitted. The comprehensive analysis suggested that Handan bentonite could meets the demand of the quality of feeding additive.
