Zusammenfassung:	The invention discloses a preparation method for modifying CuCo2O4 by utilizing rice hull biochar. The preparation method comprises the following steps: step 1, taking a certain amount of Co (NO3) 2.6 H2O, Cu (NO3) 2.3 H2O and biochar RHBC, uniformly mixing, and calcining in a muffle furnace to obtain a sample; and step 2, washing the sample with ultrapure water, then washing the sample with ethanol, and then carrying out vacuum drying to obtain RHBC-CuCo2O4. The invention also provides an application of the RHBC-CuCo2O4 obtained by the preparation method in activating persulfate to remove pollutants in water. The composite material is environmentally friendly, the metal leaching rate is low, and organic pollutants in water can be efficiently removed in the advanced oxidation process based on peroxysulfate. 本发明公开了一种利用稻壳生物炭改性CuCo2O4的制备方法，包括如下步骤：步骤1、取一定量Co(NO3)2·6H2O、Cu(NO3)2·3H2O、生物炭RHBC混合均匀后放入马弗炉中煅烧得到样品；步骤2、将所述样品先用超纯水洗涤，再用乙醇洗涤，之后真空干燥得到RHBC-CuCo2O4。本发明还提供上述的制备方法得到的RHBC-CuCo2O4在活化过硫酸盐去除水中污染物中的应用。该复合材料环境友好,金属浸出率
