By the deoxidization of zero-valent iron,nitrobenzene,an organic compound hard to be biodegraded,can be deoxidized to nitrosobenzene,and further to aniline,which is easily biodegraded.
We propose that As anomalism in groundwater possibly resulted from the combined effects of organic matter-enriched lacustrine sediments, geological setting and topographical characteristics.
Superoxide dismutase(SOD) in eggs can inhibit the photoreduction of nitro-blue tetrazolium (NBT).Thisreaction can be used to quantitatively determine the enzyme activities of SOD.
The main body of a book is adopt to follow different condition of admeasurement in vitro to active effect of stem tumour mustard hydrogen nitrate reductase.
Chloroamine T oxidization resin, a new solid phase agent for iodination is prepared.The synthesis conditions are studied and the oxidation reduction properties of the resin are determined.
The feasibility of roasting reduction method to dezinc the Zn bearing BF dust was proved by energy spectrum analysis and differential thermal(DT) and thermo gravimetric(TG) analysis firstly.
And it mainly includes the action of 1,3-diethylene alkylation and acidyl; the action of addition of carbonyl compound; the action of chlorortrimethys:lane and the reaction of diethy lene.
