HERNANDEZ DOM¨ªNGUEZ %A PEDRO HERN¨¢NDEZ %J Journal of Electrochemical Science and Engineering %D 2013 %I %R 10.5599/jese.2013.0031 %X A differential pulse voltammetry (DPV) method has been applied for the first time for determination of trans-Pt[Cl2(OH)2(dimethylamine)(isopropylamine)]. To this end, all chemical and instrumental variables affecting the determination of trans-Pt[Cl2(OH)2(dimethylamine)(isopropylamine)] were optimized. From studies of the mechanisms governing the electrochemical response of trans-Pt[Cl2(OH)2(dimethylamine)(isopropylamine)], it was concluded that it is an electrochemically irreversible system with a reduc-tion under diffusion control, with a reduction potential of -425 mV. Under optimal conditions, the variation in the analytical signal (Ip) with trans-Pt[Cl2(OH)2(dimethylamine)(isopropylamine)] concentration is linear in the 0.8 ¦Ìg mL-1 to 20 ¦Ìg mL-1 range, with an LOD of 97 ng mL-1 and a LOQ of 323 ng mL-1, RSD = 1.58 % and Er = 0.83 %. The optimized method was applied to the determination of trans-Pt[Cl2(OH)2(di-methylamine)(isopropylamine)] in biological fluids, human urine and synthetic urine %K Trans-Pt[Cl2(OH)2(dimethylamine)(isopropylamine)] %K differential pulse voltammetry %K biological fluids %K human urine %U http://www.jese-online.org/Articles/Vol_03/No_2/Pdf/jESE_Vol3_No2_p81-89_2013.pdf
