Abstract
People are completely dependent on groundwater for drinking and irrigation in distant Iraq. In many places, copper ions are one of the primary pollutants found in extra quantities in groundwater. The current work uses watermelon shell for removing of copper ions from groundwater. An initial concentration of 10 mg / L and an adsorbent particle size of 1 mm were used to examine the working parameters: PH, dosage, and contact time using STATISTICA and WinQSB software. The optimization technique was set to predict the optimum conditions. However, the efficiency of the watermelon shell was more than 80% and the maximum capacity for adsorption was 9.57 mg / g under optimum conditions such as: 8 for PH, 1 g / L for adsorbent dosage and 2.5 hours for contact time. The general findings verified that the shell of watermelon is an outstanding and alternative adsorbent to remove Cu(II) from groundwater of Iraq.
