摘要

为了快速检测和分析丙酮

提出了一种利用光解和催化转化作用的间接检测方法。采用紫外线和催化剂对环境气体中的丙酮蒸汽进行分解

使其转化为CO2

再利用电化学原理检测CO2含量

从而实现对丙酮的间接检测。催化剂采用纳米工艺制备的TiO2

其作用是通过增大催化剂的比表面积和禁带带宽

提高TiO2的催化效率

加速了丙酮的反应速度

实验证明:利用紫外线和TiO2的催化转化方法

可以实现丙酮的定量分析

测量误差约为±6%

满足实际检测的需要

Abstract

To measure and analyze gaseous acetone fastly

a indirect analyzing method based on photolysis and catalysis transformation is researched.Ultraviolet radiation and catalyst can transform acetone to CO2.Acetone can be detected by analyzing CO2 with an electrochemistry sensor.Nanotechnology can enhance TiO2 catalysis efficiency and reaction speed of acetone because of the increasing of specific surface area and width of the forbidden band.The experiment proves the feasibility of analyzing gaseous acetone by catalysis transformation and ultraviolet radiation.The measurement error is ±6 % and the need of application is met.
