- Description
- The objective of this paper is to present a co-precipitation technique with calcium carbonate for removal of heavy metals ions from oil field brine. Metals such as Mercury, Copper and Lead can be removed by the co-precipitation technique. In this work, parameters such as pH, injection time and concentration of reactants were optimized in other to obtain maximum removal efficiency. The results showed that pH has a significant effect while the injection time and reactant concentrations were less effective to remove the metals. Based on the SEM, ICP and hydrometer analysis, the optimum experimental conditions were the pH of 10, the injection time of 20 min and the reactant concentration of 0.5 mol percent. Approximately, more than 90 percent of mercury, lead and copper was removed employing co-precipitation techniques with calcium carbonate. Scanning Electron Microscopy analysis indicates that 200 rpm is the optimum rotational speed which leads to the formation of small particles. Finally, this study showed especially that the co-precipitation technique is a good alternative to remove the heavy metals especially mercury from the contaminated oil field brine.
