臭氧在金属氧化物上的分解机理

臭氧分解反应在环境科学中具有重要理论和实际意义。本文对近期相关文献进行了综述，对臭氧在固体催化剂表面上的吸附和分解过程进行了总结，并结合我们的实验对其分解机理进行了探讨。     

分散蓝2BLN染料的二氧化氯氧化脱色研究

我们用CIO2氧化分散蓝2BLN,对其进行脱色,在1分钟内脱色率为90％以上。在最佳条件下,研究了反应的动力学。用PMS半经验方法计算了2BLN分子的键级。结果表明,脱色反应的级数,对2BLN为1级,对CIO2为0．5级,这个反应是十分快的,开始于一个Sn2亲核历程。     

活性炭吸附法处理苯乙酸工艺废水中甲苯的模拟研究

Active carbon has been widely used to treat wastewater.In this paper active carb on adsorbent is used to treat methylbenzene resulting from the production of phenylacetic acid.Our experiment indicates that acidity has no effect on adsorb ability.At temperature 22℃ and flow rate 1Bv/h,adsorption efficiency of methyl benzen is 94.2% and erasing rate of CODCr reaches 94.9%.Alkaline-alcohol solution is employed as an eluent to regenerate active carbon.After regeneratio n,adsorption efficiency of methylbenzene is 86.4% and the erasing rate of COD Cr is 87.3%.
