"Dowex 50" is a type of ion-exchange resin, called a strongly acidic cation exchanger, used for ion-exchange chromatography. It is useful for swapping a metal cation for a proton (eg. Na+ for H+) or one metal cation for another (eg. K+ for Na+). This can be an important way for purifying amino acids, carboxylate salts or removing unwanted metal ions from water solutions.

Synthetic resins method forremoval of permanent hardness ofwater?
A method for blowing synthetic resins as a fuel into a furnace comprising: processing synthetic resins consisting essentially of film shaped synthetic resins by melting or semi-melting the synthetic resins by heat to produce granular synthetic resins having a bulk density of at least 0.3 and angle of repose of up to 40 degrees; pneumatically feeding the granular synthetic resins from the processing; and blowing the pneumatically fed granular synthetic resins into a furnac
