| 摘 要： | 研究了粉状磺化煤加到Fe3O4结构中制备磁性磺化煤,这种吸附剂能够有效地吸附许多有机化合物,用含三苯甲烷、杂多环和偶氮基等水溶性有机染料进行测定.结果表明吸附平衡时间为30-90 min,最大吸收能力在每1 mL吸附剂可吸附9-18mg染料或每克干吸附剂可吸附115-230 mg染料.对刚果红和结晶紫的吸附服从Langumir吸附等温线,而对于亚甲基蓝和苯胺蓝的吸附则服从Freundlich吸附等温线.图4,表2,参9.

| Abstract: | Magnetic solphonated lignite was prepared by entrapment of fine solphonated lignite particle into the structure of magnetic iron oxides. The adsorbent could efficiently adsorb a vatiety of organic dyes belonging to the triphenylmethane, heteropolyeyclic and azodye groups were used as model compounds. The results show that the adsorption of the tested dyes reaches equilibrium in approximately 30-90 min; max.iumum adsorption capacities ranged between 9 mid 18 mg of dyes per 1 mL of the sedimented adsorbent ;this corresponds to 115-230 mg of dyes per 1 g of the dried adsorbent. Adsorpytion of congo red and crystal violet can be described using the Langmuir isotherm, on the other hand, adsorption of methylene blue and aniline blue can be described using a Freundlich isotherm. 4figs., 2tabs,, 9refs. |
