Use of NaX porous materials in the recovery of iron ions

Nowadays, the porous materials have an economic impact in certain industrial fields and particularly that of the environment. NaX materials economically prove very interesting; small quantities of these last are enough to treat great toxic volumes of effluent. This work aims at the use of NaX solid materials in the recovery of the ions iron poisons and vermin to the environment. We used a treatment process based on ions exchange reactions. Several parameters related to these operations of treatment were studied and the used materials are types of NaX faujasites. The obtained results show that NaX faujasite and its hydrogenated form NaHX can be used like ion exchangers in the recovery of the ions iron Fe3+. NaX and NaHX materials preserve their crystalline structures during the treatment process until 0.2 mol/l Fe3+ concentrations.
