The joint toxicity was evaluated by different methods, including toxicity unit,additive index, similarity parameter and mixtures toxicity index. The results show that the binary joint effects of phenol and toluol mixed with SDS are synergistic, while the binary joint effect of SDS and nitrobenzene is antagonistic. The environment risk of some compounds will be enhanced because of the joint of SDS.
研究结果表明: 4种不同的评价方法对SDS与取代芳烃苯酚、甲苯和硝基苯的联合效应评价结果具有较好的一致性,即SDS与苯酚、甲苯的二元混合体系的毒性表现为不同程度的协同作用,而与硝基苯则表现为弱拮抗作用;对环境存在风险性的阴离子表面活性剂SDS,当与一些有毒有害物质共存时会增加该类物质的环境风险性。

The carboxyl of the tripodal ligand is a goodbridging group. The building blocks are linked together by the bridging group andother weak interactions (hydrogen bond and π-π stacking interaction, etc), thusgenerating a one, two or three-dimensional metal complexes.2. Studies on the fluorescence properties of the lanthanide complexes indicated that:(1) The excitations in the ligand-based π-π〓 transitions cause the structuredemission of lanthanide complexes while the ligand luminescence is completelyquenched showing that ligand-to-metal energy transfer occurs.
