The effect of aluminum electrode distance in electrocoagulation as a reductor of heavy metal lead (Pb) in water: An environmental health study
Keywords:
electrode distance, lead (Pb), voltage, currentAbstract
Electrocoagulation uses an aluminum electrode toreduce lead in water through a chemical reaction. The previous study employed a voltage of 20 volts, a current of 10 amperes, and a contact time of 60 minutes to reduce lead. This follow-up study is still being conducted on a laboratory scale in order to determine the ideal electrode distance. The study's goal was to examine the influence of electrode spacing of 15 cm, 17.5 cm, and 20 cm on the decrease in lead in water at a voltage of 20 volts and a contact period of 60 minutes. The study had a true experimental design with a post-test only control group. Data gathered from 6 replications of 4 treatments, with the factors pH and current strength taken into consideration. The results revealed a difference in lead decrease. The difference occurred at 15 cm electrode distance with a drop of 0.018 mg/liter and 20 cm electrode distance with a decrease of 0.024 mg/liter. pH and current strength did not affect the decrease in lead in variations in the distance of the reactor electrode. The best lead reduction occurred at the Aluminum electrode with a distance of 20 cm.
