The invention relates to a method for detecting rich husk ash, and belongs to the technical field of chemical materials. The invention provides a method for detecting rich husk ash which includes thedetermination of absorbance of rich husk ash extract. The invention also provides a method for detecting rich husk ash which includes the detection of the relative content of 4-coumaric acid in rice husk ash. The methods of the invention can conveniently and effectively identify the quality of the rice husk ash and judge whether the rice husk ash is qualified and whether the rice husk ash is suitable for preparing high-performance white carbon black. The method is simple in operation, is low in requirements on equipment, and can help rice processing enterprises improve the economic added valueof rice husk ash products and improve the performance of the white carbon black. 本发明涉及种稻壳灰的检测方法，属于化工材料技术领域。本发明提供种稻壳灰的检测方法，包括测定稻壳灰提取液的吸光度。本发明还提供了种稻壳灰的检测方法，包括检测稻壳灰中4-香豆酸的相对含量。通过本发明的方法，可以方便有效鉴别稻壳灰的品质，判断稻壳灰是否合格，以及是否适用于制备高性能的白炭黑。本
