In the late 60 ‘s on recovery of molybdenum from industrial wastewater by ion-exchange reports. So far,
Macroporous Weak Base Anion Exchange Resin the remains of molybdenum-containing wastewater by ion-exchange techniques. Zhang Jianguo, studying low-molybdenum polymer 201×7 acid sturdy base anion exchange resins on adsorption mechanism of said low-molybdenum acid polymer and resin of molybdate exchange price substantially slower. The reason, assume low-molybdenum acid polymer is primarily with six Exchange polymers and resins, with 4 polymer adsorption of molybdate.
Resin and gel pore size is quite small, so the low price big diffusion resistance of molybdenum acid in polymer resin, resulting within a reduced exchange price. While molybdate adsorption on polymeric resin at low rates is slow, but molybdenum salt exchange positions occupied on the resin ‘s, are extra strongly bonded with resin and harder than resin of molybdate adsorption and desorption. Only together with the oxidizer (for instance 1mol/LHNO3) oxidation to desorption somewhat rapidly.
Macroporous Weak Base Anion Exchange Resin Resulting from the acidic circumstances, Mo (VI) would be the decreasing agent to restore for low-molybdenum, low-molybdenum acid polymers not just simply exchanged with resin and Elution and more trouble. Consequently, it is best to take away the decreasing agent within the therapy of molybdenum-containing wastewater, its best adjusted to pH values above 7.
