摘要
研究了太阳光照下,水溶液中FeC l3-三氯乙醛的光化学反应速率,采用紫外分光光度计定时对含有不同浓度Fe(Ⅲ)的溶液进行实验测定,并根据三氯乙醛标准溶液曲线进行分析。实验结果表明,在波长为480nm的紫外光照射下:室内自然光下含有Fe(Ⅲ)和室外太阳光下不含Fe(Ⅲ)的三氯乙醛溶液中,三氯乙醛的浓度基本保持不变;但在室外太阳光下含有Fe(Ⅲ)的三氯乙醛溶液中,三氯乙醛的浓度随着Fe(Ⅲ)浓度的增加而减小。由此表明,Fe(Ⅲ)是三氯乙醛光化学反应的催化剂,FeC l3-三氯乙醛的光化学反应随着Fe(Ⅲ)浓度的增加而加快。
The light of the sun,the solution FeCl3-Chloral the photochemical reaction rate,ultraviolet spectrophotometer used regularly to contain different concentrations of Fe(Ⅲ) the solution of the experiment,and in accordance with standards of chloral Solution curve analysis.Experimental results show that in the wavelength of 480 nm ultraviolet irradiation: Indoor under natural light with Fe(Ⅲ) and outdoor sunlight is non-Fe(Ⅲ) of chloral solution,the concentration of chloral basically Unchanged,but in outdoor sunlight contains Fe(Ⅲ) of chloral solution,the concentration of chloral with Fe(Ⅲ) the increase in the concentration decreases.This shows that,Fe(Ⅲ) chloral photochemical reaction is a catalyst,FeCl3-Chloral the photochemical reaction with Fe(Ⅲ) to accelerate the increase of concentration.
