Determination of gold in drugs and serum by use of anodic stripping voltammetry.
نویسندگان
چکیده
Gold is determined in aqueous gold-containing drug solutions, 8 X 108 to 1 X 10 mol/liter, and in such drugs in serum, 2 X 106 to 1 X 10 mol/ liter, by electrodeposition onto a carbon paste electrode at -0.3 V vs. a saturated calomel electrode and subsequent stripping at constant current. Aqueous solutions are prepared for electrodeposition with a ceric perchlorate-hydrogen peroxide treatment. Serum samples are in addition treated with nitric and chloric acids. Variation coefficients are 16 to 2.5%, depending on concentration and deposition time.

An efficient protocol for the selective oxidation of primary alcohols to aldehydes withH5IO6/V2O5 in ionic liquid [bmpy][PF6] has been developed. High yields of the products, mildreaction conditions and simple experimental procedure make this protocol complementary tothe existing methods. The catalyst can be reused for several times without obvious loss of thecatalytic activity.

Anodic stripping voltammetric determination of Pb, Cd, Zn and Cu in blood samples of 132 children was developed. The children's ages range was between 6 months and 6 years and the samples were collected from different areas of Ibb governorate (Yemen). We used anodic stripping voltammetry for analyzing and determination of cited metals in the blood of all children. Large variation in the results...
