Abstract:
Details of fabrication of a low cost polarograph is described. Price of components, electronic circuitary, the procedure and performance are detailed. The total cost of the fabrication of the polarograph, if assembled from the local resources, should be around US$ 100. The polarograph, composed of a power supply and a potentiostat, is small (dimensions 2x(20x15x15 cm), light weight (4 kilos), stable and accurate enough for routine and educational work. The polarograph was tested with cd2+ pb2+ , Zn2+ , Cu2+ , and MV2+ and found to reproduce satisfactorily the literature values of E1/2,s.
