Product specification THOMAPOR ® -membranes "RP" for acid dialysis are produced... more

Product specification

THOMAPOR®-membranes "RP" for acid dialysis are produced by grafting an anion-exchange monomer in low-pressure polyethylene. The introduction of these small chain segments renders the membrane hydrophilic.

THOMAPOR®-membranes "RP" have a low resistivity in acid media. They are best suited for recovery of acids out of pickling solutions, for copper refining and electroplating solutions. The support film consists of HDPE (high density polyethylene). The graft type is weakly anionic.

Electrodialysis membranes have always to be kept wet and should be stored in a 3 % NaCl solution in a cool and dark place.

Technical specification

Resistivity: <20 m x Ohm/inch2 (related to 12°Be H2SO4 after 336 h reflux in 30 % H2SO4)

Dialysis: H2SO4 flow: 2.4 x 10-2 eq./min/inch2 (related to a solution of 300 g H2SO4/l and 30 g FeSO4 x 7 H2O/l in dist. water at +20 °C); Fe2+ flow: 2.1 x 10-6 eq./min/inch2 (related to a solution of 300 g H2SO4/l and 30 g FeSO4 x 7 H2O/l in dist. water at +20 °C)

Width extension: 5.6 % (in 12°Be H2SO4)

Length extension: 4.4 %
