Improving Iron and Copper Uptake by Changing the Ratios in Root of Vetiver Grass

Abstract Phytoremediation using Vetiver grass (VG) has been used in the past few decades all over world, but effectiveness of its uptake mechanism water less discussed especially mixed metal conditions. Hence, focus this research was to determine and evaluate heavy removal two metals, copper (Cu) iron (Fe), based on vetiver toxicity. Three treatments Fe Cu mixture were chosen, individual concentrations act as a control. The at height 10 cm root length 25 for each treatment harvested days 0,1, 3, 6 7. roots randomly cut, oven-dried digestion method extract root. From result, better ability compared treatment. is increasing up 25.3 % presence (mixture 1). Meanwhile, Cu, 3 an ideal ratio increase by 14.5%. It shows that both facilitated other’s real wastewater There also observed minimal toxicity signs such necrosis throughout experiment. appearance changed experiment starting day remains yellowish. In conclusion, contains high concentration than can promise improvement grass. This study benefits researchers apply phytoremediation remove metals providing guideline future, will interaction
