Abstract

Liquid waste containing heavy metals such as lead (Pb), cadmium (Cd), and nickel (Ni) is a serious environmental problem because it is toxic and difficult to degrade naturally. One effective method to overcome this problem is electrocoagulation using aluminum electrodes. The purpose of this study was to determine the effect of pH variations on the removal efficiency of Pb, Cd, and Ni metals using the electrocoagulation method on artificial waste. The study was conducted with pH variations of 3, 5, 7, 9, and 11, with an initial concentration of each metal of 20 mg/L. The parameters analyzed included the final concentration and metal removal efficiency. The results showed that pH significantly affected the performance of electrocoagulation, with optimum efficiency obtained at pH 9. The highest removal efficiency for each metal was Pb at 99.35%, Cd at 97.50%, and Ni at 99.70%. Under these conditions, Al(OH)₃ species are formed, which act as active coagulants in the adsorption and flocculation of heavy metals. These results indicate that the electrocoagulation method is highly effective for treating waste containing heavy metals.Keywords - Aluminum, Electrocoagulation, Heavy Metals, Ph, Removal Efficiency.

Abstract

This study aims to determine the quality of the waters of Sungsang, Banyuasin Regency, South Sumatra Province based on several water quality parameters and determine the level of lead accumulation of heavy metals (Pb) in the white shrimp network (Penaeus merguiensis) to the abiotic environment (water and sediment) based on the value of Bioconcentration Factor (BCF). This research is expected to be able to contribute to the calculation of Ocean Health Index (OHI) as an important indicator for the ongoing assessment of marine health that can be used as a database in making marine policy. Based on the results of the study obtained the results of the heavy metal content of Pb in water and sediments in the waters of Sungsang have not exceeded the quality standards set by South Sumatra Governor Regulation No. 16 of 2005 and based on standard sediment quality guidelines for metals and associated levels of concern to be used in doing assessments of sediment quality in 2003 and according to the IACD / CEDA (International Association of Draging Companies / Central Dreging Association) in 1997. Lead metal concentrations contained in white shrimp produced from three locations have exceeded the limits set by the Head of BPOM RI No HK.00.06.1.52.4011 in 2009. Based on the value of Bioconcentration Factor (BCF), the absorption of Pb in the white shrimp network (Penaeus merguiensis) to its abiotic environment at the three research sites in the waters of Sungsang, Banyuasin Regency, South Sumatra Province shows a low accumulative level.
