Pure Magic ® GC 120 Strong Acid Cation Exchange Resin

Description of Pure Magic ® GC 120 Strong Acid Cation Exchange Resin

Application

⚫ Water softening

⚫ Preparation of pure water

⚫ Wet metallurgy

⚫ Rare element separation

Precautions

⚫ Resin should be wet state preservation. The best temperature is above 0℃. Resin should

be put into a closed space or add in salt water of 5% or above if not used for a long

time.Should be anti-freezing during transportation. Do not place heavy objects on the resin

in case being crashed.

⚫ Generally requires alkali- water – acid – water flow path for processing. Strict requirement

needs three circulation before coming to final ion kenel.

⚫ Need to consider different transformation expansion rate to set aside enough space to

prevent resin overflow and ensure the appropriate liquid level height; Column diameter

ratio should be within a reasonable range and avoid bias current; Use wet packed column

or back-flushing to wash away bubbles inside resin layer.

⚫ Before liquid going into the resin column, steps as flocculation, filtration, or sand-filtration

should be taken so that it doesn’t jam resin pore with suspended solids .

⚫ Resin inside the column that hasn’t been used for a long time should be storaged outside

of the column after washing, or adding salt water in the salt resistant medium while keeping

liquid level not dehydrated with usual backwashing to loosen resin in case of

agglomeration.
