  volatile organic compounds
    However, the low quantum efficiency (~ 4 %) of photocatalytic process has awfully hindered the industrialization. In this paper, the H_2-O_2 synergistic effect on photooxidation of volatile organic compounds (VOCs) on Pt/TiO_2 and Pt/TiO_2-xNx has been investigated for the first time.

The volatile organic pollutents in water of DuKou Segment of Jinsha River were analyzed by capillary GC-FID and capillary GC-MS methods. The water samples were first enriched by chromosorb-105, then the enriched samples were eluted with CS2. 97 organic compounds were detected from thesamples with quantitativetive data for 50 compounds therein. The maximum concentration of individual compounds is 0. 4 ppb and the average concentration for the 50 compounds is 36 ppt. It is not serious as compared with other rivers...

The volatile organic pollutents in water of DuKou Segment of Jinsha River were analyzed by capillary GC-FID and capillary GC-MS methods.

According to the requirments of statement of work for organic analysis and its quality assurance/quality control (QA/QC) of US EPA contract laboratory program (CLP), The inter-standard quantitative analysis of semivolatile organic compounds in waste water has been perfomed in China for the first time. 16 kinds of compounds belonging to the prior pollutants of US EPA method including 4 kinds of prior pollutants in China have been detected in secondary treatment sewage of a sewage treatment plant.Their concentrations were between 3. 12 and 41. 4 ng which less than emission standard values permitted. 9 kinds of trail compounds which less than emission standard values permitted. 9 kinds of trail compounds which are non-toxic,such as aliphatic hydrocarbon,carbohydrate and the acids were between 1. 3 to 39. 9ng. The analytical speed can be elevated by adopting this method,and its results are very reliable. The secondary treatment effluents of this sweage treatment plant meet the requiment for national emission standard.
