The effects of hydraulic loading and NaCl concentrations on the regeneration of exhausted homoionic natural zeolite.

چکیده
A study of the suitable operational conditions for the regeneration of exhausted homoionic natural zeolite with ammonium was carried out. Laboratory-scale columns using NaCl solutions with concentrations of 2 and 4 mol/L and hydraulic loadings of 4, 6 and 8 bed volumes per hour (BV/h) were assessed. For both NaCl concentrations studied, the hydraulic load of 6 BV/h showed the highest ammonia nitrogen output from the exhausted zeolite bed. Results showed that the hydraulic load (BV/h) had a greater influence on the regeneration efficiency than the concentration of the regenerating solution.

Removal of PAHs from n-Paraffin by Modified Clinoptilolite
The ability of natural clinoptilolite and its modified forms were studied for removal of PAHs from n-paraffin. Surfactant modified zeolite (SMZ) was obtained by modifying clinoptilolite with hexadecyltrimethylammonium ion. Homoionic forms of zeolite were obtained by ion exchange process using inorganic salts of desirable cations (e.g. Ag+, Fe3+…). Nat...

In this work, SO2 adsorption on 13X and 5A was explored at different concentrations, and the results were compared to molecular simulation and models. The adsorbent saturation tests were performed at four different concentrations of 250, 500, 750, and 1000 ppm, and it was observed that saturation would take more time for higher SO2 concentrations. Grand Canonical Monte Carlo method was used for...
متن کاملPreparation, characterization and photocatalytic degradation of methylene blue by Fe3+ doped TiO2 supported on natural zeolite using response surface methodology
The photocatalytic degradation of methylene blue was investigated with TiO2 and Fe2O3 nanoparticles supported on natural zeolite. The synthesized photocatalyst was characterized by XRD, XRF, FT-IR, EDX, FE-SEM, and BET analyses. The results of XRD, FT-IR, and EDX confirmed the successful loading of Fe3+ doped TiO2 nanoparticles on natural zeolite. Further, the FE-SEM results confirmed the depos...

An improved chemical regeneration of the granular activated carbon (GAC) exhausted by the color (pigments and pollutants) from citric acid fermentation solution (CAF) was investigated. In the experiments, improved means were adopted to advance the traditional chemical regenerating method and the adsorption capacity of the first time renewed GAC is 103% of original GAC. Using oxidan...
