Fe(NO3)3-太阳光催化降解双酚A的研究

Photocatalytic Degradation of Bisphenol A in the presence of Ferrum (Ⅲ)

摘要:

采用Fe(NO3)3为催化剂，在自然光照射下对双酚A的降解过程进行了研究。考察了Fe(NO3)3用量、体系的pH值、双酚A初始浓度、光照时间等因素对双酚A降解效率的影响，并测定了双酚A的CODCr去除率。结果表明，当Fe(NO3)3和双酚 A 摩尔比为0.8：1、体系pH为3、双酚A初始浓度为10 mg/L时，经太阳光照射降解三天，双酚A 的降解率可达到99.4%，其COD去除率可达到66.8%。

Abstract:

The photocatalytic degradation of bisphenol A (BPA) in aqueous solution with the Fe(NO3)3 catalyst by sunlight irradiation was investigated. The effects of dosing quantity of Fe(NO3)3 , PH, initial concentration and irradiation time on bisphenol A are discussed during the degradation process of BPA. CODCr removal of BPA was determined. The experimental results showed that under the optimum condition, i.e., the mole ratio of ferric nitrate and BPA was 0.8:1, pH value was 3 and the concentration of BPA was 10 mg/L, three days irradiation by sunlight, the removal of BPA was 99.4%, and the COD mineralization rate was 66.8%.
