Nitrate Removal from Aqueous Solution by Using Modified Clinoptilolite Zeolite
Background & Aims of the Study: Nitrate is one of the most important pollutants that its reduced form, nitrite, can cause serious problems for human health and environment. Adsorption with cheap sorbents such as Zeolite is the best way for removal of this pollutant. So this study aimed to apply modified Clinoptilolite Zeolite for nitrate removal. Materials & Methods...

متن کاملRemoval of Dimethyl Phthalate from Aqueous Solution by Synthetic Modified Nano Zeolite Using Cu2O Nanoparticles
In this paper, a novel nano crystalline sodalite was synthesized and characterized by XRF, XRD, SEM and FTIR analysis. Cu2O nanoparticles (30-60 nm) were loaded on nano zeolite bed and utilized as an adsorbent to remove dimethyl phthalate. The SEM-EDX of modified zeolite indicates that the amount of copper loading on the zeolite was 4.5 wt%. Modified nano zeolite was used as an effective adsorb...
متن کاملSimultaneous phosphate and ammonium removal from aqueous solution by a hydrated aluminum oxide modified natural zeolite
A natural zeolite (Z-N), rich in clinoptilolite, was modified (Z-Al) by incorporation of hydrated aluminum oxide (HAlO) for the simultaneous phosphate and ammonium removal. The incorporation of surface hydroxyl groups (≅Al-OH) into the zeolite structure, as active groups for phosphate removal, was characterized by acid-base titrations (pHPZC=4.5±0.2). The phosphate sorption increases from 0.6 m...
متن کاملRemoval of Fe2+ from Aqueous Solution Using Manganese Oxide Coated Zeolite and Iron Oxide Coated Zeolite
The adsorption of Fe2+ by the manganese oxide coated zeolite (MOCZ) and iron oxide coated zeolite (FOCZ) was studied. Surface properties of adsorbents have been investigated for monitoring their changes and morphology for both of the MOCZ and FOCZ. Main variables namely; contact time, pH, initial concentration of Fe2+, size and dosage of adsorbent have been optimized, and the results contrasted...
