钠蒙脱石的d 001间距从9.87埃增加到17.50埃后，在pH 2.5的化合物与富里酸的相互作用。间距的大小随着pH值在2.5和6.0之间的增加而减小。pH值为2.5时，40毫克的纳蒙他汀可吸附31毫克的富里酸; pH值为6.0时，仅吸附15.8毫克。
The d001 spacing of sodium montmorillonite increased from 9.87 to 17.50 angstroms after interaction of the compound with fulvic acid at pH 2.5. The magnitude of the spacing decreased with increase in pH between 2.5 and 6.0. A t pH 2.5 40 milligrams of Namontmorillonite adsorbed 31 mg of fulvic acid; at pH 6.0, only 15.8 mg.
