Synthesis and Modification of Clinoptilolite [PDF]

open access: yesMolecules, 2017
Clinoptilolite is a natural mineral with exceptional physical characteristics resulting from its special crystal structure, mainstreamed into a large zeolite group called heulandites. An overall view of the research related to the synthesis, modification and application of synthetic clinoptilolite is presented.

Encapsulation of Cs/Sr contaminated clinoptilolite in geopolymers produced from metakaolin [PDF]

open access: yes, 2015
The encapsulation of caesium (Cs) and strontium (Sr) contaminated clinoptilolite in Na and K based metakaolin geopolymers is reported. When Cs or Sr loaded clinoptilolite is mixed with a metakaolin geopolymer paste, the high pH of the activating solution

Fate and Impacts of Triclosan, Sulfamethoxazole, and 17β-estradiol during Nutrient Recovery via ion Exchange and Struvite Precipitation [PDF]

open access: yes, 2017
Increasing emphasis on resource recovery from wastewater highlights the importance of capturing valuable products, e.g., nutrients such as nitrogen and phosphorus, while removing contaminants, e.g., organic micropollutants. The objective of this research

Removal of silver (I) from aqueous solutions with clinoptilolite [PDF]

open access: yes, 2006
The aim of the present work was to investigate the ability of natural zeolite, clinoptilolite, to remove silver ions from aqueous solution. Towards this aim, batch adsorption experiments were carried out and the eect of various parameters on this removal

Species sensitivity of zeolite minerals for uptake of mercury solutes [PDF]

open access: yes, 2006
The uptake of inorganic Hg2+ and organometallic CH3Hg+ from aqueous solutions by 11 different natural zeolites has been investigated using a batch distribution coefficient (Kd) method and supported by a preliminary voltammetric study.

Zeolita, estudio de aptitud como una puzolana natural aplicada a hormigón estructural [PDF]

open access: yes, 2015
Nowadays, concrete is one of the most widely used construction materials due to its low price, appropriate mechanic characteristics and durability. Also, due to its ease to adopt diverse forms and sizes (Najimi et al., 2012).

Use of Clinoptilolite in Ethanol Dehydration [PDF]

open access: yesSeparation Science and Technology, 1996
Clinoptilolite-type natural zeolite, which exists in various regions of Turkey, has been experimentally studied. For the ethanol-water-local clinoptilolite system, uptake and breakthrough curves were determined under a nitrogen gas atmosphere. In adsorption kinetics and adsorption equilibrium studies, the effects of particle size, temperature and ...

Characterization of natural Yemeni zeolites as powder sorbents for ammonium valorization from domestic waste water streams using high rate activated sludge processes [PDF]

open access: yes, 2018
BACKGROUND In this study three natural Yemeni zeolites (NZ1, NZ2 and NZ3) having major minerals such as clinoptilolite and mordenite, were evaluated as low cost sorbents for the removal and recovery of ammonium ions.

H2 separation using pressed clinoptilolite and mixed copper‐clinoptilolite disc membranes

open access: yesThe Canadian Journal of Chemical Engineering, 2016
AbstractDisc membranes machined from high‐purity natural clinoptilolite rocks demonstrated promising hydrogen separation efficiency. However, these membranes cannot be adequately scaled up. To overcome this and provide process flexibility, mixed matrix membranes are required, pairing small particles of natural zeolite with a binder system.

Use of a zeolite synthesised from alkali treated kaolin as a K fertiliser: Glasshouse experiments on leaching and uptake of K by wheat plants in sandy soil [PDF]

open access: yes, 2011
Zeolite N, a zeolite referred to in earlier publications as MesoLite, is made by caustic reaction of kaolin at temperatures between 80 °C and 95 °C. This material has a very high cation exchange capacity (CEC ≈ 500 meq/100 g).
