From experimental study on removal of heavy metals from wastewater by adsorption of some low-cost, such as peanut husk charcoal ash particles. SEO natural light to get rid of Cu2 + and Zn2 + ion, using variables such as pH values. Duration of exposure Quantity, concentration, using the dilution solution with distilled water. Experiment at 27 ± 2° c and a pH value that is absorbing Zn2 + and Cu2 + ion removal well at pH 6-8 to get rid of the metal for the first time 30 minutes for Cu2 + metal removal and Zn2 + in 2-3 hours.
