The influences of environmental factors on the abiotic methylation were studied. The biggest production of methylmercury was found after 2 days of incubation in presence of FA. The rate of production of methylmercury depends upon temperature. In presence of FA from sediment, the biggest production of methylmercury was found under 40℃. In presence of FA from soil, production rate increases with temperature. The biggest production of methylmercury was found when solution pH was 2 and 4 in presence of FA from sediment and soil, respectively. Increase in concentrations of inorganic mercury and FA solution causes an increase in the production of methylmercury. Under irradiation with ultraviolet ray, blacklight lamp as well as natural light, methylation is stimulated, especial for irradiation of ultraviolet light.

环境条件对汞甲基化作用的影响研究得出，在底泥和土壤FA体系中甲基汞产量均在反应2天后达到最大值；在底泥FA体系中汞的甲基化在反应温度为40℃时产量最大，而在土壤FA体系中，甲基汞产量在10～60℃之间随反应温度升高而增加；底泥和土壤FA体系中汞的甲基化分别在pH值为2和4时最大；甲基汞产量均随无机汞浓度和腐殖质浓度的增加而增加；紫外线、黑光灯和自然光照射都可促进甲基汞的生成，紫外线的作用尤其明显。

objective: to prepare the molecularly imprinted composite membranes with propofol as template.methods: with the ultraviolet light and initiator, template molecular propofol, functional monomer methacrylate and crosslinking agent ethylenegly-coldimethacrylate formed molecularly imprinted composite membrane through polymerization on the surface of polyvinyli-dene fluoride microporous membrane.inspection of the combination of template molecule and functional monomer, characterization of the membrane surface morphology with scanning electron microscopy.results: the morphology of composite membranes was well.propofol bonded to methylacrylic acid with hydrogen bond.conclusion: the method of ultraviolet light-struck is feasible for preparation of molecularly imprinted composite membranes with propofol as template.

目的：制备异丙酚分子印迹复合膜。方法：在紫外光照和引发剂的作用下，模板分子异丙酚、功能单体甲基丙烯酸和交联剂乙二醇二甲基丙烯酸酯在聚偏氟乙烯微孔滤膜表面聚合形成分子印迹复合膜，考察模板分子和功能单体的结合特性，用扫描电镜表征膜的表面形态。结果：复合膜形态良好，异丙酚和甲基丙烯酸以氢键的方式缔合。结论：用紫外光照射法可以制得异丙酚分子印迹复合膜。

Since the effect of ultraviolet radiation on synthetic polymers is similar to its effect on the human skin, it is not surprising that ultraviolet stabilizer s such as phenyl salicylate have been used for many years in suntanning lotions.

因为紫外辐射对合成的聚合物的作用类似于它对人体皮肤的作用，所以紫外线稳定剂如水杨酸苯基酯多年来一直被用作防晒液也就不足为奇了。
