Effect of TiO2 surface properties on the SCR activity of NOx emission abatement catalyst

NOx emission abatement catalysts V2O5 supported on various TiO2 including anatase, rutile and mixture of both were investigated with various physico-chemical measurements such as BET, NH3-TPD, NARP, XRD and so on, and the effect of TiO2 surface properties on the SCR (selective catalytic reduction) activity of V20s/TiO2 catalysts was studied. It was found that the TiO2 surface properties had strong affect on the SCR activity of V2Os/TiO2 catalysts. The stronger acidic property resulted in the higher exposure of active sites as well as the higher SCR activity.

Development of thermochromic strips as a water pasteurization indicator

Boiling of water, for purification, commonly practiced in the world, has many problems associated with it like danger of scalding,scaling in the vessels, removal of useful minerals and blandness of taste etc. Water can be made safe for drinking simply by heating at 65℃ for 6 minutes. A colour indicating strip was developed which changes colour from red to purple at 67℃. Use of this strip can help in pasteurizing water without the above problems and with considerable energy saving.     

吸烟对室内空气的影响及防治措施

在当今世界，人们在关注室外污染的同时，更应该把目光投入室内污染，特别是吸烟对室内空气的影响。本文论述了香烟烟者对室内环境所造成的污染，重点介绍了由香烟烟雾引起的室内污染对健康的影响，并提出了防治措施。     

人工湿地基质渗滤特性及净化污水效果

以细沙、细沙和碎石质量比为1∶1、1∶2、2∶1的三种组合,以及煤渣和壤土质量比为1∶1的混合物共五种基质为供试对象,通过比较测定不同基质渗透性,选择渗透性较好的基质搭配填入人工湿地模型中,测定进出水水质,研究基质对系统净化污水的效果.结果表明,渗透性对人工湿地系统净化污水有一定影响,当基质渗透性较好、孔隙率较高时,污水总磷、氨氮、以及化学需氧量去除率较高;随时间延长,各指标去除率降低,其中总磷去除率与时间有较好的线性相关.
