研究了盐酸四环素的降解动力学模型。通过不同的升温速率(β=5、10、20、25K/min)下进行热重量分析得到降解数据,并根据无模型动力学方法,得到降解活化能E及其与反应转化率α之间的关系(在转化范围0<α<0.3内,E的平均值为200kJ/mol;当α>0.3时,E值随着α变化而变化)。 The degradation kinetic model of tetracycline hydrochloride was studied. Degradation data were obtained by thermogravimetric analysis at different heating rates (β = 5, 10, 20, 25 K / min), and according to the model-less kinetic method, the degradation activation energy E and its reaction rate α (Within the transformation range 0 <α <0.3, the average value of E is 200 kJ / mol; when α> 0.3, the value of E varies with α).
