    PENGURANGAN KADAR LOGAM BERAT Cr PADA LIMBAH ELEKTROPLATING MENGGUNAKAN METODE ELEKTROKOAGULASI
    (Elfitra, 2022-09) Adelya, Yuriska; Hanifah, T. Abu
    Electrocoagulation is a method that has been successfully used for the treatment of metal plating waste. The principle of the electrocoagulation method is based on oxidation and reduction reactions. This study used variations in voltage, length of time for electrocoagulation and speed of stirring in electroplating wastewater treatment. Based on the results of the study, The voltage of 10 volts has a chromium metal content value of 1.9 mg/L with a metal reduction percentage of 70.31%. The electrocoagulation time of 240 minutes has a chromium metal content of 0.033 mg/L with a metal reduction percentage of 99.48%. The stirring speed of 150 rpm has a chromium content of 0.1 mg/L with a metal reduction percentage of 98.43%. The stirring speed of 150 rpm has a large agglomerate morphology. The results of elemental analysis using Energy Dispersive X-Ray (EDS) showed that the flocculant contained an elemental carbon (C) of 5.17%. The elemental content of oxygen (O) is 50.95%. The elemental content of aluminum(Al) is 28.78%. The elemental content of chromium (Cr) is 12.15%..
