【摘要】 采用光化学方法对室内空气污染进行检测与治理,研制测量治理一体化的空气净化材料,通过溶剂萃取法从天然玫瑰中提取玫瑰色素,采用玫瑰色素色素和硫酸羟胺组成超分子探针,用溶胶-凝胶法制作甲醛传感膜,负载于纸质材料上,组装为功能纸玫瑰饰件。利用智能CCD设备测量颜色变化信号,基于图像识别和色彩坐标处理,计算甲醛浓度并判断污染状况。更多还原

【Abstract】 The formaldehyde had been identified as a carcinogenic and teratogenic molecule,which was the most common indoor air pollutant.To solve the problem of indoor air pollution caused by the formaldehyde,a supramolecular probe was designed in which a natural dye extracted from the rose was used.The formaldehyde sensing film was prepared using the sol-gel method.A formaldehyde-responsive papery ornament was then fabricated.The chromatic data were collected by the CCD and then processed by the software based on the Android platform.The pollution level of the formaldehyde was evaluated by the expert system.更多还原
