environmental sample
4.The progress on state analysis of metal in environmental sample with combination techniques of AAS and other methods in home and obroad since 1985 arc summarized and 86 references arc extracted in this paper.
5.The V2 region of the 16S ribosomal DNA of the ammonia-oxidizing bacteria (AOB) was amplified directly from the environmental sample by using the specific PCR primers. The purified PCR product was cloned into T-vector and was identified as 16S rDNA fragment of AOB by sequencing and Real-time PCR method. Then, the recombined plasmid was used as standard molecule sample in Real-time PCR for AOB quantification.
6.Solid phase extraction(SPE) technology,which is one of environmental-friendly technologies of sample pretreatment,was employed in the trace analysis of Butylbenzyl phthalate(BBP).
7.The montane elfin forest could be divided into 5 kinds, samples of nearby sites had strong comparability, the more close the place was, the more similar vegetation type and environmental factor were, the smaller the difference of the sample was.
8.Environmental soil samples were determined by SPE-HPLC/ESI(-)-MS. The concentration of TBBP-A in soil sample was 25.2±2.7 ng/g (n=4).
9.SPE (solid phase extraction) as a technique of sample pretreatment for aquatic environmental pollutants analysis is reviewed.
10.Molecularly imprinted polymer can be used to highly selective separation and enrichment of trace analyte in complicated biological, medicine and environmental samples because of its characteristics of high selectivity, chemical stability, easy preparation, so the application of molecular imprinting technique in sample pretreatment was especially remarkable.
