| Abstract | Adsorptive cathodic stripping voltammetry was used for the determination of furazolidone (FZ) and furaltadone (FD) in borax and phosphate buffers, respectively, using HMDE as working electrode. The influence of different factors upon the peak current response such as accumulation potential, scan rate, preconcentration time, pH and other variables was studied.Furazolidone and furaltadone showed an adsorption character on HMDE in presence of borax and phosphate buffers, respectively. A single cathodic peak at −0.36 V in borax (pH = 9.5) was observed for FZ, while FD gave a cathodic peak at −0.32 V in phosphate buffer (pH = 8.5).The calibration graph showed a linear behavior over the range 3×10−9–9×10−8 mol dm−3 for furazolidone. In the case of FD, concentrations from 3×10−9 to 2×10−7 mol dm−3 gave a linear relationship with the peak current. A detection limit of 2×10−9 mol dm−3 and 1×10−9 mol dm−3 was obtained for furazolidone and furaltadone, respectively. This method was applied to determine these drugs in pharmaceutical formulations, urine and serum samples. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
