建设环境友好型社会是中国建设和谐社会的必然选择解读"十一五"

必须加快转变经济增长方式。我国土地、淡水、能源、矿产资源和环境状况对经济发展已构成严重制约。要把节约资源作为基本国策，发展循环经济。保护生态环境，加快建设资源节约型、环境友好型社会，促进经济发展与人口、资源、环境相协调。推进国民经济和社会信息化，切实走新型工业化道路。坚持节约发展、清洁发展、安全发展。实现可持续发展。 发展循环经济，是建设资源节约型、环境友好型社会和实现可持续发展的重要途径。坚持开发节约并重、节约优先，按照减量化、再利用、资源化的原则，大力推进节能节水节地节材。加强资源综合利用。完善再生资源回收利用体系。全面推行清洁生产。形成低投入、低消耗、低排放和高效率的节约型增长方式。[编者按]

表面活性剂对分枝杆菌KR2生长的影响

研究了表面活性剂的浓度、离子类型和分子结构等对分枝杆菌KR2菌株生长的影响。结果表明，一些表面活性剂在低浓度时可以促进分枝杆菌KR2的生长，高浓度时则会抑制KR2菌株的生长。表面活性剂的离子类型对KR2菌株生长抑制作用的顺序为：阳离子活性剂TDTMA＞阴离子表面活性剂LAS＞非离子表面活性剂Tween80。表面活性剂的直链长度对KR2菌株生长的影响为：直链越短，对分枝杆菌KR2菌株生长的抑制作用越大。     

膜分离技术处理电镀废水的实验研究

采用纳滤＋反渗透2级处理系统浓缩回收电镀铜漂洗废水。实验结果显示：在△P=1．5MPa条件下进行浓缩．纳滤膜可以使料液浓缩近10倍。纳滤膜对Cu^2＋的截留率在96％以上，对COD的截留率在57％以上。在△P=3．0MPa条件下进行浓缩，反渗透膜可以使料液浓缩近10倍。反渗透膜对Cu^2＋的截留率在98％以上，对COD的截留率在67％以上。随着料液浓度的增加，纳滤膜和反渗透膜的截留率会降低。

Adsorption selectivity of salicylic acid and 5-sulfosalicylic acid onto hypercrosslinked polymeric adsorbents

Both bottle-point and column-feeding experiments involving different solutes and sorbents were carried out to investigate the adsorption selectivity and separation performance of salicylic acid and 5-sulfosalicylic acid. Their adsorption isotherms onto such hypercrosslinked polymeric adsorbents as NDA-100 and NDA-99 could be well described by the Freundlich equations whose characteristics describe extrathermic and favorable adsorption processes. The adsorption towards NDA-100 mainly depended on the π-π interaction, while that towards NDA-99 was extremely influenced by the static-electric interaction. Additionally, the adsorptive capacity of salicylic acid on NDA-99 decreased while it increased on NDA-100 with the presence of 5-sulfosalicylic acid in the adsorptive environment as the competitive component. Comparatively, the adsorption capacity of 5-sulfosalicylic acid decreased on both resins with salicylic acid as the competitive component. In fact, the difference in the interaction between adsorbent and adsorbate resulted in the straight antagonism on the effective adsorption sites on the adsorbent. In conclusion, the adsorption selectivity of salicylic acid onto NDA-100 was obviously larger than that onto NDA-99 with the existence of 5-sulfosalicylic acid in the adsorptive environment. A satisfactory separation and recovery of tested solutes in aqueous phase could be foreseeably achieved by the sequencing adsorption technique involving NDA-100 as well as NDA-99.
