Solution
The correct option is D Electro-dialysis
The process of removal of soluble impurities from a colloidal solution through a semipermeable membrane is called dialysis. The apparatus used for this purpose is called dialyser. The process is quite slow and gets completed in many days. the process is quickened by the passage of electric current. this is called Electrodialysis.this method is used for the removal of non-electrolyte impurities very fast.
