Environmental Changes Deduced from Grain-size Characteristics of the Sediments from Hongjiannao Lake,Shaanxi Province;

Notes on wetland birds in Hongjiannao lake of Shaanxi province;

A 0.1 ka-year Record of Environmental Evolution in Hongjiannao Lake, Shaanxi Province;

Protective situation and countermeasureson Larus relictus(Laridae) in Hongjiannao wetland of Shannxi Province;

Preliminary study of Hongjiannao Lake s variation and ecological water demand;

The Research on Marketing Strategy of Hongjiannao Scenic Spots;

Hongjiannao wetland,located on the migratory route of birds in China and an area of concentrated distribution of waterfowls,was the main spot for resting and reproduction of Larus relictus and waterfowls in migration.

Water supply and consumption of Hongjiannao watershed during 1998-2004 were calculated with generalized methods and a water balance model was established.

Study on photocatalytic degradation of basic violet and mechanism in UV/TiO_2 suspension system;

The degradation of basic violet by electrogenerated H_2O_2-TiO_2/UV system was investigated in this paper.

Degradation of basic violet by solo electrolysis and solo photocatalysis, and degradation of eosin and basic violet by electrolysis-photocatalysis were investigated.

Determination of Trace Nitrite by Catalytic Spectrophotometry with Basic Fuchsin

The adsorption performance of steel slag to basic fuchsin dye and the affecting factors were studied,and the microwave degradation of dye adsorbed on steel slag-coke was investigated.

A method has been developed for the determination of trace iron(Ⅲ) based on the fact that iron(Ⅲ) can catalyze the oxidation of basic fuchsin by hydrogen peroxide in H 2SO 4 medium.
