【摘要】 对上海市老港填埋场封场6-10年矿化垃圾中的胡敏酸(HA)进行荧光光谱分析,结果表明,不同封场时间的矿化垃圾中HA的荧光光谱均为宽带峰型,pH值对HA荧光光谱的影响较小.而且随着矿化垃圾封场时间的加长,荧光特征峰波长缓慢增加.更多还原

【Abstract】 The aged refuse with a placement age of 6 to 10 years were sampled from Shanghai Laogang refuse landfill. The humic acids(HA)product was extracted from humic substances and analysed by fluorescence spectra. It was demonstrated that fluorescence emission spectra of all the HA products has broad peak, the impact of the pH to the fluorescence spectra was negligible, and the wavelength of peaks for HA products increased slowly with the increase of humidification extents.更多还原
