| 中文摘要: |
| 通过单因素实验研究了盐酸羟胺/Fe2+/过硫酸盐体系中pH值、盐酸羟胺投加量、Fe2+投加量、S2O82-投加量对氯霉素处理效果的影响,确定的最佳条件为:pH值为3.0,盐酸羟胺投加量为7.0 mg/L和Fe2+投加量为60.0 mg/L,S2O82-投加量为61.2 mg/L。基于单因素实验,利用响应面优化模型得到的氯霉素降解率影响因素显著性大小的顺序为:盐酸羟胺投加量＞Fe2+投加量＞pH值＞S2O82-投加量。利用模型得到的优化条件为:pH值为4.0,盐酸羟胺投加量为6.0 mg/L,Fe2+投加量为62.0 mg/L和S2O82-投加量为61.0 mg/L。在此优化条件下,氯霉素降解率的模型预测值(87.41%)与实验值(84.61%)相对误差较小,由此证明了模型的合理性。 |
| 英文摘要: |
| Single-factor experiments were conducted to investigate the effects of pH, hydroxylamine hydrochloride dosage, Fe2+ dosage, and S2O82- dosage on chloramphenicol degradation in a hydroxylamine hydrochloride/Fe2+/persulfate system. The optimal conditions were determined as follows: pH=3.0, hydroxylamine hydrochloride dosage=7.0 mg/L, Fe2+ dosage=60.0 mg/L, and S2O82- dosage=61.2 mg/L. Based on the single-factor experiments, response surface optimization modeling reveals that the order of significance of influencing factors on chloramphenicol degradation rate is: hydroxylamine hydrochloride dosage > Fe2+ dosage＞pH＞S2O8-2 dosage. The optimized conditions derived from the model are: pH=4.0, hydroxylamine hydrochloride dosage=6.0 mg/L, Fe2+ dosage=62.0 mg/L, and S2O82- dosage=61.0 mg/L. Under these conditions, the model-predicted chloramphenicol degradation rate (87.41%) closely matches the experimental value (84.61%), with a small relative error, which confirms the model’s validity. |
