| titleOfInvention | Electroosmose process is separated the method for complex state DTPA and hardness ions |
| abstract | The invention discloses a kind of method that electroosmose process is separated complex state DTPA and hardness ions, the step of the method is as follows: first in the anolyte compartment and cathode compartment of electrodialysis unit, be filled with Nan 2 sOn 4 solution, is filled with sulphuric acid soln to sour room, is filled with solution to salt room; Then the waste water containing DTPA and hardness ions complex compound is passed into separate chamber, start direct supply, hydrogen ion selective now in sour room is through cationic membrane, enter separate chamber, the waste water pH value in separate chamber is made to drop to less than 3, DTPA and hardness ions generation dissociation reaction, form free DTPA anion radical and hardness ions, hardness ions continues selectivity and enters salt room through cationic membrane, DTPA anion radical to adjacent sour room and the migration of salt room, thus cannot achieve being separated of DTPA and hardness ions.Method of the present invention can large-scale industrial production; Achieve being separated of DTPA and hardness ions, decrease discharge of wastewater, be conducive to environment protection; Reclaim valuable DTPA solution, realize the target of recycling. |
