Therefore, the aim of this project is to examine and investigate the total removal of copper Cu2+ from local industrial wastewater using chemical precipitation method. This research is investigating the removal efficiency of Caustic Soda NaOH as precipitant agent during hydroxide precipitation process. The experimental work consists of ten samples of real spent rinse wastewater from local electroless nickle plating company containing copper Cu2+ as a heavy metal with a concentration of 1000ppm. Also, 0.5M of sodium hydroxide NaOH solution was prepared and added to the wastewater samples with different volumes during titration process. In order to examine how effective and efficient the process was, important parameters such pH, Cu2+ percentage reduction and mass of precipitates were investigated and taken into account with respect to volume of NaOH and time reaction. The results can be concluded that the optimum values for pH, Cu2+ percentage reduction and mass of precipitates are 7.75, 99.95% and 0.0283g respectively, and were obtained at 1.2ml volume of NaOH and 2 hours of time reaction. Since those results meets standard A of local standards discharge limits, they are most recommended to wastewater treatment plants to be used in a larger scale in order to have a proper treatment before discharging to the river. 2023-05-03T16:47:52Z 2023-05-03T16:47:52Z 2020-02 https://irepository.uniten.edu.my/handle/123456789/21403 application/pdf
