Question

use ion exchange method in analytical separation to separate mercury and nickel from polluted water using analytical steps and protocols.

Expert Solution

Step 1

Basically the river bodies are polluted by the heavy metals like Cadmium,Mercury,nickel.
Mainly they are originated from metal planting ,mining,battery manufacturing company .
They are very hazardious to human health .If the heavy metal containing water directly discharged to the water sources then it will be fatal to the aquatic system.
Its concentration is high upto 300 mg/ Liter and it must be treated for reusable water.

Step 2

Ion exchange is a water treatment method used to remove dissolved ions.
Ionic substance removed from water by applying ionic attraction and repulsion theory.
The two types of ion exchange method are anionic exchange and cationic exchange .
Cationic exchange is used for the positively charged attractive particles and anionic exchange is used for the negatively charged particle.
