紫外光芬顿-膜分离耦合体系降解金霉素

以金霉素为降解对象，采用沉淀法制备α-FeOOH光催化剂，进一步将其用共价结合法负载在陶瓷膜上，用SEM、XRD、EDS、UV-Vis和FTIR对α-FeOOH和光催化陶瓷膜进行表征.结果表明催化剂α-FeOOH呈针状或纺锤长片状，长宽分别为500~550nm、25~50nm，经α-FeOOH改性的陶瓷膜孔隙率由14.83%变为8.11%.研究光芬顿陶瓷膜耦合体系对金霉素的降解效率和动力学行为，确定了光芬顿陶瓷膜耦合体系的最优降解条件为金霉素初始浓度50mg/L，H₂O₂投加浓度10mmol/L，UV强度为3796.6μW/cm².进一步利用UV-Vis光谱分析了两种体系对金霉素的降解机理，光催化剂体系下，H₂O₂的浓度基本保持不变，而光芬顿陶瓷膜耦合体系下H₂O₂的浓度先升后降，同时后者在同一时间点对TOC和NH₄⁺-N去除率更高，表明光芬顿陶瓷膜耦合体系氧化能力更强，对金霉素的降解更为彻底.

Comparison of Black Carbon,Total Organic Carbon,and PAH Concentrations in Surface Sediments from Two Main Rivers in Henan Province,China

Black carbon (BC) in surface sediments from Henan section of Yellow River and Huaihe River, China, was determined. Average content of BC in Huaihe River was 0.33%, higher than that in Yellow River (n?=?23) with mean value of 0.15%. Distribution patterns of BC in Yellow River and Huaihe River were similar, namely that tributaries had higher BC content than main stream. In addition, BC content in the mainstream of Yellow River and Huaihe River decreased with altitude. The BC content presented a significant positive correlation with clay (r?=?0.672; p?<?0.01) content in Yellow River, while neither did in Huaihe River. The ratio of BC/TOC ranged from 1.8–57.4% (median 29.6%), evidencing pyrogenic fossil fuel source of BC in Yellow River. Relatively low values of BC/TOC in Huaihe River (5.3%–28.8%, median 7.5%,) reflected that the origin of BC is from burning of biomass. In addition, Pearson rank correlation analysis showed that BC was in strong correlation with lighter PAH in Yellow River, while BC was in significant correlation with heavier PAH in Huaihe River. The ratio of BC/TOC indicated that BC in Yellow River mainly came from fossil fuel combustion, while BC in Huaihe River was primarily from biomass burning.

Photochemical reduction of hexavalent chromium in glycerol-containing solutions

Hexavalent chromium [Cr(VI)] in the form of potassium dichromate was photochemically reduced to trivalent chromium [Cr(III)] in aqueous solutions containing glycerol. This reaction occurred rapidly during irradiation with either unfiltered sunlight or a UVA-emitting light source. Photochemical reduction of Cr(VI) was pH-dependent and did not occur in dilute solutions of sodium hydroxide. In acidified solutions, the reduction occurred at elevated rates and at lower concentrations of glycerol. This reaction was found to be dependent on the unsubstituted alcohol groups of glycerol since alpha-phosphoglycerol and beta-phosphoglycerol did not support the photochemical reduction of Cr(VI). These findings suggest that glycerol or related polyols can be used for the remediation of hexavalent (toxic) chromium at contaminated environmental sites.
