Abstract:

以3种标准粘土矿物伊利石、高岭石和蒙脱石为材料,研究其中红外光谱(包括透射光谱、衰减全反射光谱和光声光谱)的特征。3种粘土矿物的中红外透射光谱均存在3个主要的吸收区域(3000~3800cm-1,1300~1800cm-1和500~1200cm-1),且吸收特征明显不同;3种粘土矿物的中红外衰减全反射光谱的差异主要表现在800~1200cm-1,其他区域差异不明显;而3种粘土矿物的中红外光声光谱特征与透射光谱相近,但3个吸收区域具有更丰富的吸收特征。应用中红外光声光谱分析表明,海伦黑土为富含蒙脱石的偏中性土壤,长武黄土为富含蒙脱石或伊利石的碱性土壤,而祁阳红壤为富含高岭石的酸性土壤。
