title: [The fluorescence properties of DaYaWan soil humic acid].
abstract: The fluorescence properties of humic acid derived from DaYaWan soil were analyzed using the conventional fluorescence and synchronous scan fluorescence spectroscopy. The results show that synchronous technique applied to the study of humic acid can reduce the fluorescence spectrum of a compound to a single sharp peak, and decrease the signal overlapping. In addition, the effects of various deltalambda, concentration and pH values on synchronous fluorescence spectroscopy were investigated in detail.
