Review on performance of native plants in removing heavy metals in wastewater / Nurul Aiman Haziqah Abdullah

Heavy metals are considered extremely harmful because they can cause illness and diseases to human and environment. Wastewater that discharges from many sources like wastewater from industry can lead to water pollution if untreated especially due to its high concentration of heavy metals. Therefore wastewater containing heavy metals should be treated before discharge to the water stream. This study are focused on identifying potential plants in Malaysia that can remove heavy metals in wastewater and evaluate the performance of various native plants in removing heavy metals in wastewater. There are several methods to remove heavy metals like adsorption, chemical precipitation, reverse osmosis, and ion exchange. However those methods usually are very costly. Therefore this study focused on phytoremediation method which is environmental friendly and economic. The phytoremediation concept is the best technology to be used in order to solve the water pollutant. It is very suitable to apply in developing countries like Malaysia. The methodology in this research is focused on the several experiments that have been done by previous researchers. From the experiment, it can be seen that a few study area in Malaysia with the sample of plants and wastewater that taken in the site. The results show the performance of the plants that use in their experiment which give a good result in removing heavy metals in wastewater.
