中文摘要：

系统研究了油页岩渣合成沸石过程中NaOH浓度、熔融温度、晶化时间、晶化温度对沸石生成及其Cr^6＋吸附性能的影响．结果表明，NaOH浓度和晶化时间主要影响沸石的种类；沸石对Cr^6＋的吸附率随其制备的熔融温度、晶化时间、晶化温度的增加有增大的趋势，但随NaOH浓度降低而增加；沸石对1mg／L含铬模拟废水中Cr^6＋的最大吸附量为1．120mg／g，吸附率达到89．6％．考虑到成本，最佳合成条件为：NaOH浓度4．6mol／L，熔融温度400℃，晶化时间72h，晶化温度140℃．

英文摘要：

The formation and Cr^6＋ adsorption capability of zeolite synthesized after alkaline activation of a Chinese oil shale residue, and the effects of NaOH concentration, fusion temperature, aging time and aging temperature in closed systems on its adsorption to Cr^6＋ were investigated. NaOH concentration and aging time affected mainly the crystallinity of zeolite formed. Cr^6＋ adsorption capability of synthesized products increased with increasing fusion temperature, aging time and aging temperature. Cr^6＋ adsorption capability of synthesized zeolite decreased with the increase of NaOH concentration, reached its maximum adsorption capacity and adsorption rate for simulated 1 mg/L Cr^6＋ polluted water were 1.120 mg/g and 89.6% respectively. From the economic point of view, the optimal conditions are determined as follows： NaOH concentration of 4.6 mol/L, fusion temperature of 400 ℃, aging time of 72 h, and aging temperature of 140 ℃.
