A novel nano-SnO2/graphite electrode has been prepared via polishing procedure to produce active and stable surface. The modified electrode resolves the overlapping voltammetric response of dopamine and ascorbic acid.into two well-defined peaks by 230 mV. The mechanism of discrimination of dopamine from ascorbic acid.is discussed. Dopamine and ascorbic acid.can be determined simultaneously with the modified electrode. The electrode shows good sensitivity, selectivity and stability.

Electron transfer (ET) from ascorbic acid.(AA) in aqueous to ferrocene (Fc) in1,2-dichloroethane (DCE) was probed by the scanning electrochemical microscopy (SECM). Therate constants were extracted from the dependence of the steady-state current at ultramicro-electrode(UME, tip) on the distance between the tip and the phase boundary by comparison to theoreticalworking cures.

Molybdenum (Mo) deficiency and nitrogen contamination have been proved to be relevant to the higher incidence of esophageal cancer. In order to reduce the amount of nitrate and nitrite in grains and vegetables, ammonium molybdate has been used as a trace-element fertilizer in Linxian County, a high risk area of esophageal cancer. This supplementation has significantly raised the yield and the Mo content of the crops. The nitrate and nitrite levels in crops and vegetables were reduced by 12-53 and 20-32% respectively. The amount of ascorbic acid.in vegetables which can block the in vivo synthesis of nitroso compounds is increased by 10-70%.Taking the inhibitory effect of Mo on cancer into account, Mo supplement by using Mo fertilizer probably can serve as an effective chemoprevention measure against this disease in high risk areas.
