“…Among physical, biological and chemical advanced oxidation methods the last one seems to be most promising due to its rate, efficiency and no post-treatment problems in the majority of processes. Various methods were applied for BP and OP elimination from water environment like sonolysis of OP (Yim et al, 2003), BP photosensitized oxidation using simulated solar radiation (Gryglik et al, 2009), ozonation (Ning et al, 2007) or OP degradation in the TiO 2 /UV system (Yamazaki et al, 2008). The direct photolysis (254 nm) of BP (B"ędzka et al, 2009a) and of OP (Mazellier and Leverd, 2003) was found to be inefficient due to low quantum yield.…”

“…It also belongs to a kind of endocrine disrupting compounds (EDCs) owe to the fact of causing modifications of sexual development and reproductive function in wildlife [2]. In regard to the removal of 4-t-OP or other EDCs, TiO 2 photocatalyst has been attempted to photocatalytically decompose these chemicals under ultraviolet light irradiation, since the catalyst have shown some advantages, such as optical-electronic properties, low cost, high photocatalytic activity, chemical stability and non-toxicity [3][4][5][6].…”

The photocatalytic decomposition of 4-t-octylphenol (4-t-OP) by NaBiO(3) photocatalyst and the catalyst stability in aqueous solution were investigated systematically for the first time. The results showed that some parameters such as catalyst dosage, initial 4-t-OP concentration and pH value of the solution had great effects on the photocatalytic activity. The NaBiO(3) photocatalyst maintained considerable catalytic performance under visible light (lambda>400 nm) irradiation and exhibited a higher photocatalytic activity compared to the commercialized photocatalyst P25. In addition, the corrosion products of NaBiO(3) catalyst under acid condition (HCl aqueous solution contained) were characterized by X-ray diffraction (XRD), transmittance electronic microscopy (TEM), selected area electron diffraction (SAED), X-ray photoelectron spectroscopy (XPS) and UV-vis transmittance spectrum analysis. The results showed that NaBiO(3) was unstable under the acidic condition and the catalyst could convert into Bi(3+)-containing compounds such as Bi(2)O(3), etc. The experiment demonstrates that NaBiO(3) can be corroded to nano-sized BiOCl crystal in the presence of hydrogen chloride, the band gap of which was estimated to be 3.28 eV by Tauc's approach.

“…Many researchers have studied on degradation of phenolic compounds as well as BPA [19][20][21][22][23][24] and OP [25][26][27] using ultrasonic and photocatalytic degradation technique. However, to the best of our knowledge, comparative study of these two techniques has not been explored much so far.…”

“…Thereafter with further increase in catalyst loading to 200 mg/L, the degradation rate starts declining. This is due to the screening effect, that is, above a certain amount of catalyst loading (150/100 mg/L), the turbidity of the solution increases and ultraviolet rays start getting scattered, hence reducing the optical path [26]. Intermediates like hexadecane, eicosane, heptacosane and demeclocycline, tetradecane, heptacosane and hexadecanewere identified by GC-MS for BPA and OP degradation.…”

A B S T R A C TBisphenol A (BPA) and 4-tert-octylphenol (OP) are well-known endocrine disrupting compounds. Ultrasonic and photocatalytic degradation of BPA and OP were carried out by optimizing different parameters such as effects of the pH, ultrasonic frequency, power and the dosing amount of the sodium persulfate (oxidizer)/TiO 2 photocatalyst. The results showed that the maximum ultrasonic degradation of BPA and OP was obtained at a pH value of 5, 45 kHz frequency, 500 W power and with sodium persulfate concentration ranging from 100 to 200 mg/L under bubbling of air, whereas for photocatalytic degradation, maximum degradation was observed at a pH value of 5, and TiO 2 dosing ranging from 50 to 150 mg/L. Photocatalytic degradation was found to be more efficient and cost-effective than ultrasonic degradation.
