| 520 | 3 | _aDaily, hospital generates a significant amount of wastewater which is more than the consumption of domestic water. The hospital wastewater may contaminate with micro-organisms, heavy metal, toxic chemicals and radioactive elements. In fact, the hospital wastewater is generating hybrid wastewater at the same moment domestic, industrial and effluents of care and medical research. Throughout this research our main concern is to remove targeted heavy metal that found to contain in the hospital wastewater, Pb and Ni. The wastewater will be treated using the ultrasonic technology assisted with several of leaching solution, HNO3, citrate and EDTA. Ultrasonic process has been found as reliable solution which applies intense, high frequency sound to liquids, producing intimate mixing and powerful chemical and physical reactions. The best performance of these leaching solutions (HNO3, citrate and EDTA) will be studied through the main parameter such as type of solution, sonication time and concentration of the solution. The sample obtained from the hospital is filtered and spike with amount of targeted heavy metal prior to ultrasonic process and AAS analysis. As the result, the best time to remove Pb is 3 minutes while 6 minutes for Ni removal. The suitable concentration to remove Pb is 0.06 M while 0.1 M for Ni. The percentage removal is 54% for Pb and 35.93% for Ni. | |
