Photodegradation of o‐Cresol with Ag Deposited on TiO2 under Visible and UV Light Irradiation

This study investigated the effect of dosage of Ag on the characteristics of TiO₂, quantum yield, and temporal decomposition behavior of o‐cresol in an annular reactor under ultraviolet (UV) and visible light irradiation. In order to extend light absorption and minimize the rapid recombination during photoreaction, the Ag deposited on TiO₂ photocatalysts was prepared by a photodeposition process. The results of diffuse reflectance spectra (DRS) indicated that Ag deposited on TiO₂ promoted the optical absorption in the visible region and made it possible for it to be excited by visible light. The degradation rate of o‐cresol with 0.50 wt % Ag/TiO₂ under visible light irradiation was 2.0 times that with pure TiO₂.

研究了三光气（BTC）与邻甲酚反应合成碳酸邻甲酚酯的新方法，并对酚钠盐浓度、温度、三光气用量等因素的考察。结果表明：酚钠盐浓度、温度以及BTC用量过高或过低，都会降低收率，其中温度较高会加速BTC的分解，而BTC用量较低会使反应不完全。合成碳酸邻甲酚酯的优化工艺条件为酚钠盐浓度为2．8moL／L，温度25℃，三光气用量为5．1g，收率98．45％，纯度达98％以上。     

Influence of the Abaeté River on the reproductive success of the neotropical migratory teleost Prochilodus argenteus in the São Francisco River,downstream from the Três Marias Dam,southeastern Brazil

The curimatã‐pacu Prochilodus argenteus is an important characiform from the São Francisco River basin that performs long‐distance migrations for spawning upstream during the rainy season, when the temperature and photoperiod are elevated. Despite the interruption of the migratory routes by the Três Marias Dam and accentuated decline in fishing, the curimatã‐pacu still sustains the fisheries at the Três Marias region in recent decades. The objective of this study was to evaluate the reproductive activity of P. argenteus in two sections of the São Francisco River, downstream from the Três Marias Dam, during the rainy season. In the first 34 km of the river, immediately below the dam, most of the females were in gonadal resting. At 34–54 km downstream from the dam, following the confluence with a medium‐sized tributary, the Abaeté River, there was a high frequency of males and females in reproductive activity. Follicular atresia was more frequent in the upper section of the river while postovulatory follicles occurred predominantly in the lower section. Fulton's condition factor and gonadosomatic index indicated that the females were in a better physiological and reproductive condition below the confluence with the Abaeté River. In contrast to the females, the males were less affected by damming, and testicular maturation was largely achieved in two river sections. Thus, although the section of the São Francisco River immediately below the Três Marias Dam was found to be unfavourable for the reproduction of the migratory fishes due principally to the hypolimnetic water from the reservoir, reproductive success of P. argenteus was achieved below the Abaeté River. In this section, the species encountered appropriate conditions for maturation and spawning, i.e. warm temperatures above 24°C, high water flow and dissolved oxygen, and low water transparency. These results indicate the importance of a non‐regulated tributary to minimize the ecological impact of a dam on the downstream native fish communities. Copyright © 2005 John Wiley & Sons, Ltd.     

Hydrogen formation by the photodecomposition of water over Pt/TiO2 suspended in a water in oil emulsion

Hydrogen formation by the photodecomposition of water has been successfully achieved in a water in oil emulsion (w/o emulsion) system containing Pt/TiO₂. The hydrogen formation rate was affected by the amount of water added to the emulsion. It was concluded that water in the w/o emulsion containing Pt/TiO₂ was more active than free water for the photodecomposition to form hydrogen.

218Po测氡法再探

测氡法在应用于油气勘探时，取样装置及测试条件均须改进。改进后的装置主要增加了一个密封胶环，这不仅起到了封闭作用，而且还对保护管起到了定位作用；测试条件的改进主要是延长取样时间１分钟，将原孔深３５ｃｍ增加到１５５ｃｍ。改进后的装置在文３１油藏的测试中，记数率平均达８０脉冲／ｍｉｎ以上，平面图上环状异常形态清楚，且测出了负异常。
