Determination of Lead in Waste Water Using Cyclic Voltammetry by Platinum Wire Electrode
Determination of lead in waste water using cyclic voltammetry by platinum wire electrode hasÂ been carried out. The cyclic voltammetry method was performed in a three electrodes system usingÂ platinum wire as a working electrode, an Ag/AgCl (saturated KCl) as reference electrode and platinumÂ plate as the counter electrode. PGSTAT 100 N 100 V/250 mA type (Metrohm Autolab) was used forÂ electroanalysis measurements. Electroanalysis of lead in waste water was performed in 0.1 M KClasÂ an electrolyte. From this research showed that the developed electroanalysis lead in waste water usingÂ platinum wire electrode are accurate, precise, reproducible and inexpensive with acceptable correlationÂ of determination (R2 = 0.999), LOD = 0.9029 mg/L , LOQ = 3.0098 mg/L and recovery = 100,67%.Â The methods can be used for the analysis of lead in waste water. This method is simplicity of sampleÂ preparation and use of low cost reagents are the additional benefit.
