摘　　要：为了解决黄磷副产物磷铁附加值低的问题,采用Design Expert软件设计和优化了黄磷副产物制备磷酸铁的实验,考察了温度、反应时间和酸浓度等因素对黄磷副产物制备磷酸铁的浸取率的影响。通过响应面分析法的预测与实际实验验证,当硝酸质量分数为30%、固液质量比为1∶8、反应温度为95℃、反应时间为6 h时,实验效果最佳,浸取率可达70.5%。为黄磷副产物制备磷酸铁方法的工业应用提供了新思路。In order to solve the problem of low added value of phosphorus and iron,Design Expert software was used to design and optimize the preparation of iron phosphate by yellow phosphorus byproducts,and to investigate the influence of temperature,reaction time and acid concen-tration on the extraction rate of iron phosphate from yellow phosphorus byproducts.Through the prediction and verification of the response sur-face analysis method and the actual experiment,when the nitric acid concentration is 30%,the solid-liquid ratio is 1∶8,the reaction tempera-ture is 95℃,and the reaction time is 6 h,the experimental effect is the best,and the extraction rate can reach 70.5%,which provides a new idea for the industrial application of preparing iron phosphate from yellow phosphorus byproducts.
