Hi, Umair. Is this one beaker full of solution you must treat, or hundreds of gallons per minute?

If you are indeed a student, you need to at least attempt some portion of your assignment yourself before you simply post your homework for someone else to do :-)

If this is an actual application, you should contact a wastewater treatment company and have them confirm and clarify your analysis and propose a treatment strategy which might include chemical precipitation, ion exchange, and reverse osmosis. Good luck.
