The result showed that sodium ion content of Tamarix chinensis,Elaeagnus angustifolia,Populus alba increased gradually with the increase of irrigation year in the same vegetal part,and varied with the different desert plants,highest in of T.

A survey of the content of sodium ion in the soils and reeds irrigating with pulping and papermaking effluent was conducted.

Effect of Na++ on specific methanogenic activity(SMA)of anaerobic granular sludge,COD removal rate,effluent VFA,as well as the buffering capacity,were studied in IC reactor operation.

The combination of Na++ with alanine dipeptide (AD) in gas phase has been studied using den-sity functional theory at the level of B3LYP/6-311++G**,and six Na++-AD complexes were obtained,in-cluding two bidentate and four monodentate ones.

Objective: To explore the acute toxic mechanism of methyl tertiary butyl ether (MTBE) by detecting the changes of Fos protein, neurotransmitter γ-amino-butyric acid (GABA) and the activity of Na++, K+-ATPase, Ca2+-ATPase in the cerebellar cortex.

Reducing formation of gaseous species,which contain chlorine,potassium and sodium,can effectively abate deposit formation,slagging,corrosion and harmful pollutant emission during thermal conversion of biomass fuels.
