Abstract: | Electro analytical Procedure was developed for the trace determination of heavy metal lead inwaste water in Jaipur Rajasthan using Differential pulse polarography.ELICO CL-362 POLAROGRAPHIC ANALYSER (Make: Elico) was used for measurement of current voltage relationship (polarograms) on electrolyzing electroactiveanalytes in polarographic cell. This apparatus has three electrode assembly, dropping mercury electrode as working electrode, calomel as reference electrode and platinum as counter electrode. Dropping mercury electrode had the characteristics m = 2.422 mg/sec, t = 2.5 sec and h = 60 cm, under the conditions of Pulse Amplitude 50 mV and 6 mV/S scan ratewas used for electroanalysis measurements. Electro analysis of lead in waste water was performed in 0.10 M KNO3as correlation of determination (R2 = 0.999). Lead concentration in different water samples in Jaipur Rajasthan varies between 2.670 ppm to 5.757 ppm. Highest level of lead is reported in Sanganerteshil(Summer season) (5.797 ppm).From this research showed that the developed electroanalysis of lead in waste water using mercury drop electrode are accurate, precise, reproducible and inexpensive with acceptable the analysis of lead in waste water. This method is simplicity of sample preparation and use of low cost reagents are the additional benefit. |
