摘　　要：探讨三维电芬顿对四溴双酚A(TBBPA)的的降解效能,构建由石墨阴、阳电极和活性炭粒子电极的三维电芬顿体系,对比活性炭吸附、电芬顿及三维电芬顿对TBBPA的去除效果,探究Fe^(2+)投加量、pH、粒子电极投加量、电流密度以及共存离子对TBBPA降解的影响。实验表明,活性炭在三维电芬顿体系中不仅起吸附作用,还发挥了粒子电极作用。当初始pH为5,Na_(2)SO_(4)电解质投加量为2 g/L,Fe^(2+)为1 mmol/L,活性炭为4 g/L,电流密度为10 mA/cm^(2)时,反应90 min TBBPA降解率达97.78%。共存离子Cl-对三维电芬顿降解TBBPA有明显促进作用,NO_(3)^(-)、HPO_(4)^(2-)对TBBPA降解有抑制作用,抑制程度为HPO_(4)^(2-)>NO_(3)^(-)。由此证明:三维电芬顿法可以高效、短时降解TBBPA,明显弥补了传统工艺的不足。This study explored the degradation efficiency of three-dimensional electric-Fenton for the tetrabromobisphenol A(TBBPA),constructed a three-dimensional electric-Fenton system consisting of graphite cathode/anode electrodes and activated carbon particle electrodes.The removal effects of activated carbon adsorption,the electric-Fenton and three-dimensional electric Fenton were compared for the TBBPA.The effects of Fe^(2+)dosage,pH,particle electrode dosage,current density and coexisting ions on the degradation of TBBPA were conducted.The experiment results showed that the activated carbon did not only play a role of adsorption in the three-dimensional electric-Fenton system,but also as a particle electrode.When the initial pH was 5,the dosage of Na_(2)SO_(4) electrolyte was 2 g/L,Fe^(2+)was 1 mmol/L,activated carbon was 4 g/L,and the current density was 10 mA/cm^(2),the degradation rate of TBBPA reached 97.78%after 90 min reaction.The coexisting ion Cl-could obviously improve the degradation of TBBPA by three-dimensional electric-Fenton,but NO_(3)^(-)and HPO_(4)^(2-)could inhibit the degradation of TBBPA.Meanwhile,the degree of inhibition was HPO_(4)^(2-)>NO_(3)^(-).This study proved that the three-dimensional electric-Fenton method can efficiently degrade TBBPA in a short time,which obviously makes up for the shortcomings of the traditional process.
