Lead as a pollutant is found on lead(II) form on water waste. Soil is a medium which is flowed by water during the water cycle can filter some water. Water as a solvent can solve some metal ion due to polution of petroleum gas combustion on driving a vehicle and machinary proces which is contain lead as one of the metal ion. Accumulation of amount of lead is directed to human organ malfunction during consumtion of water which is contaminated by lead. Voltammetric anaysis is well-known applicating amalgam as an electrode which has highly toxicity that caused a problem on preparation and direct analysis of the sample on-site so bismuth base elecrrode as the option which is possible to be applicated as an electrode to substitute the apllication of copper amalgam electrode. Lead detection on the environment sample is aplicated on µgL-1 at the minimum scale, it needs electrode which is easy to be applicated that is directed to minimum cost. On-site analysis must be applicated as the purpose to minimize the analysis cost.. As the purpose of this research based on literature study on comparative between copper amalgam electrode and bismuth electrode. Bismuth electrode on this paper is made by the deposition of bismuth on glassy carbon electrode using combined by a polimer and an amalgam is made by deposition of mercuri on copper wire as the working electrode. This paper also focusing on interferring ion on both analysis using bismuth electrode and copper amalgam electrode and the possible detection limit of the working electrode. Atomic absorption spectrometry is used as the refference of the analysis which has a relative accurate to identify the ion. As the purpose of the research is to make sure that bismuth base electrode on subtitutes the amalgam based electrode to identify themetal ion on-site. Poli.merization on forming the bismuth based electrode is examined on this literature study.
