An anthracene extended viologen-incorporated ionic porous organic polymer for efficient aerobic photocatalysis and antibacterial activity.

A new conjugated ionic porous organic polymer (AN-POP), incorporated with anthracene-extended viologen, has been rationally designed and prepared to explore its dual functions in photocatalytic oxidation and bacterial killing. Compared with its anthracene-free counterpart (BD-POP), AN-POP showed a superior photocatalytic oxidation performance and antibacterial activity demonstrating the critical role of an anthracene-extended viologen structure.

Objective: To establish the solid phase extraction-gas chromatography/mass spectrometry (GC/MS) method for qualitative and quantitative determination of several herbicides, fungicides and estrogens in drinking water.

Methods: Duplicate 1 L water samples were collected from various treatment processes of different water plants. Target pollutants were extracted by XAD-2 resin from water samples and were eluted by 30% acetone-methanol.

[Formation and changes of regulated trihalomethanes and haloacetic acids in raw water of Yangtze River, Huangpu River and different treatment processes and pipelines network].

Objectives: To investigate the pollutant levels of regulated disinfection by-products trihalomethanes (THMs) and haloacetic acids (HAAs) in raw water from the Huangpu River, the Yangtze River and different treatment processes and finished water, and to explore the changes tendency in transmission and distribution pipeline network.

Methods: A total of 65 ml water samples with two replicates were collected from different raw water, corresponding treatment processes, finished water and six national surveillance points in main network of transmission and distribution, water source for A water plant and B, C water plant was the Huangpu River and the Yangtze River, respectively. Regulated THMs and HAAs above water samples were detected by gas chromatography.

[Determination of trace iodide in drinking water in Shanghai by two columns and gas chromatography with electron capture detection].

Objective: To modify and optimize gas chromatographic conditions, qualitative and quantitative method on the base of the actual national standard detection method for drinking water on testing iodide with gas chromatography, and detect iodide in drinking water of Shanghai.

Methods: Iodobutane derivative was identified by gas chromatography/mass spectrometry, then two capillary columns coupled to electron capture detector were made by qualitative and quantitative analysis. Finally, 100 ml water samples were collected respectively from raw water and finished water of three plants in which water sources were Yangtse river, Huangpu river, and inner river respectively and detected by this developed method.

Objective: To assess thyroid disruption induced by sodium pentachlorophenol (PCP) using Organization for Economic Co-operation and Development (OECD) recommended TG 407 method.

Methods: A total of 30 specific pathogen free (SPF) SD adult male and female rats were randomly divided into 3 groups, and treated with water, 0.33 and 30 mg x kg(-1)x d(-1) of PCP-Na by oral gavage for consecutive 28 days, respectively.
