| 摘 要： | 为了考察离子液体的生态毒性，研究了5种离子液体及其浓度变化对3种农作物发芽及生长状况的影响。结果表明：就种子发芽这一生态毒理指标而言，不同作物对离子液体毒性的敏感程度不同，其次序为黄瓜>玉米>白菜；在一定浓度下，离子液体对白菜、黄瓜和玉米均具有一定的毒害作用；对于所考察的5种离子液体，阴离子为卤素的［EMIM］Br和［BMIM］Cl对植物发芽和生长的抑制作用远大于阴离子为烷基硫酸酯和烷基磷酸酯的同类离子液体 ［EMIM］［ES］、［EMIM］［DEP］和［MMIM］［DMP］。这种毒性顺序可能与卤素离子对细胞膜较强的穿透能力和由于离子液体的稳定性所造成的阴阳“离子对”的共迁移有关。

| Abstract: | In order to investigate the ecotoxicity of ionic liquids(ILs),experiment on germination and growth of three seeds was carried out for five ILs at different concentrations.The results indicate that different seeds have different reaction to the ILs in terms of eco-toxicity of seed germination,and their reaction follows the order of cucumber >corn >cabbage.In addition,all ILs at definite concentrations show some toxicity to cabbage,cucumber and corn seeds,and the ILs with halide anion,viz.Br and Cl,exhibit st... |
