摘 要：
对马来酸酐改性制成的长焰煤加合物的阳离子交换性进行研究,并同氧化煤和工业吸附剂作了对比,表明其亲质子基团的解离范围宽(pK3.6～6.5)。从水溶液中吸附多价金属阳离子的能力取决于阳离子交换剂的表面性质:该加合物对Cr、Fe、Pb的吸附活性高于КБ-4阳离子树脂。

摘 要：
The cation exchange properties of flenu coal adduct modified with maleic anhydride were studied. The re- sults indicated that its dissociative range of protonphilic groups was from pK3.6 to pK6.5. The adsorption of polyvalent cations from aqueous solutions was decided by the surface properties of cation exchanger. The adduct showed higher adsorbent activation on Cr, Fe and Pb compared with the cation exchanger КБ-4.
