Relationships among the concentration of total saccharides,total nitrogen and total phosphorus in the water with algae;

Study on methods of decreasing blank absorbency in determination of total nitrogen in water;

Measurement of total nitrogen of surface water by ion chromatograph;

By evaluating and optimizing present measurement technology and typical manual methods for aquatic total nitrogen(TN) and total phosphorus(TP),a new online monitoring technology and instrument for aquatic TN and TP were developed based on ultraviolet-K2S2O8 photocatalysis spectrophotometer.

The eutrophic level was evaluated through measuring water temperature,pH,chromaticity,total nitrogen(TN) concentration,total phosphorus(TP) concentration,chlorophyll-a level(Chla),total amount of the algal cells and water tropic state index(TSI).

Analysis on Pollution Characteristics of TN and TP in Moshui Lake Sediment;

Determination of TN and TP in Water with Microwave Digestion and Flow Injection Spectrophotometry;

Removal of TN From Eutrophic Water by Lolium Multiflorum Planted on Floating-bed;

Analysis and improved methods of bland sample experiment in determining total-nitrogen in water;

Analyse of high content of total-nitrogen in Danjiangkou Reservoir;

Determination of Total-Nitrogen,Total-Sugar and Nicotine in Tobacco by FT-NIR Spectrometry;

Relationship Between Microbial Biomass N Mineralization and Total Nitrogen Mineralization in Paddy Soils of Subtropical China;

The total N in enviromental samples is commonly determined by K_2S_2O_8-spectrophotometric method,and the total P is commonly determined by phosphatic molybdenum spectrophotometry.
