The model consists of six parts: chemical species conservation equation including absorptive factor the species uptake action including detailed vertical variation of absorptive element in CL momentum exchange in CL which is repres.n.ed by a first-order closure momentum equation with an additional larger-scale diffusive term momentum exchange in ABL which is described by a complete set of the ABL turbulent statistic parameters absorptivity (or solubility or reflection) at the surface including effects of the physical and chemical characters of the species land type seasonal and diurnal variations of the meteorological variables and deposition velocity derived by distributions of the species with height in CL. Variational rules of the concentration and deposition velocity with both height and time are simulated with the model for both corn and forest canopies. Results predicted with the bulk deposition velocity derived in the paper consist well with experimental data.

Pres.n. study describes the development of a rapid, s.n.itive and selective flow injection analysis of hydrazine in the aqueous streams of purex process by liquid chromatography system coupled with UV-Visible detector. The method is based on the formation of yellow coloured azine complex by reaction of hydrazine with para-dimethy laminobenzaldehyde (pDMAB). The formed yellow coloured complex is stable in acidic medium and has a maximum absorption at 460 nm. The pres.n.e of uranium in hydrazine solution is.n.t interfering in the analysis. Under optimum condition, the absorption intensity linearly increased with the concentration of hydrazine in the range from 0.05-10 mg?L–1 with a correlation coefficient of R2=0.9999 (n=7). The experimental detection limit is 0.05mgL–1. The sampling frequency is 15 samples h–1 and the relative standard deviation was 2.1% for 0.05 mg?L–1. This method is suitable for automatic and continuous analysis and successfully applied to determine the concentration of hydrazine in the aqueous stream of nuclear fuel reprocess.n..
