Preparation of Compound Clinoptilolite Filter Material and Performance of Ammonia Nitrogen Removal Abstract This experiment utilised natural clinoptilolite powder as the main material to prepare a spherical compound filter material with a large specific surface area and high porosity by adding an adhesive and a pore-forming agent, amongst other things. This compound filter material has a favourable effect when treating domestic wastewater. The static adsorption test showed that the adsorption rate of ammonia nitrogen was 58.5 per cent when the dosage of the compound filter material was 100 g/L, the NH₄⁺-N concentration was 100 mg/L and the contact time was ...

The University of Minnesota has developed a method to improve biofuel production University of Minnesota has developed a method to improve biofuel production American scientists have developed a computer-based screening method that identifies materials capable of improving the biofuel production process. A research team from the University of Minnesota, in collaboration with Argonne National Laboratory, has led a number of studies aimed at improving the efficiency of biofuel production. Scientists propose using aluminosilicate and zeolite as molecular sieves, either to filter chemical components or to act as catalysts for chemical reactions. There are now more than 200 different types of ... Read more

The water protection – Nikos Lygeros Translated from the Greek by Athena Kehagias Since there is at last, a formal consultation regarding the water protection from agricultural fertilizers, the role of the zeolite must be promoted in this process. More specifically, it regards the approval of: Code of Good Agricultural Practice for Protection of Waters from nitrates of agricultural sources and livestock activity, which is exactly the field of action of zeolite, since it’s already used in deceleration fertilizers. And the reason is simple, since the zeolite is able to absorb ammonia and release it slowly. Consequently, it is a ... Read more

Removal of Pb(II) from Aqueous Solutions by Zeolites, Porcelanite and Sands: Correlation of Morphology and Chemical Composition to Batch Removal Efficiency Author(s) Fawwaz Jumean1*, Lucia Pappalardo1, Hani Khoury2 Affiliation(s) 1Department of Biology, Chemistry and Environmental Sciences, American University of Sharjah, Sharjah, United Arab Emirates. 2Department of Geology, The University of Jordan, Amman, Jordan. ABSTRACT Chemical compositions of natural zeolites, porcelanite (opal-CT) and local sands were determined by X-ray fluorescence (XRF) and correlated with their Pb(II) removal efficiencies. Zeolites and porcelanite were from the Mikawer, Aritain and Hannon areas in Jordan. Sands (white, red and yellow) were from the United Arab Emirates (UAE). ... Read more

Proton Adsorption Selectivity of Zeolites in Aqueous Media: Effect of Exchangeable Cation Species of Zeolites Moses Wazingwa Munthali *, Erni Johan and Naoto Matsue Department of Life Environmental Conservation, Faculty of Agriculture, Ehime University, 3-5-7 Tarumi, Matsuyama 790-8566, Japan; E-Mails: Johan@agr.ehime-u.ac.jp (E.J.); matsue@agr.ehime-u.ac.jp (N.M.) Abstract: The saturation of negative charges of zeolites by specific cations to modify their physicochemical and catalytic properties has broadened the applications of zeolites. The adsorption behavior of H+ to Li+, Na+, K+, Rb+ and Cs+-saturated Linde-type A, Na-P1, mordenite, X type and Y type zeolites was evaluated at different pH-pM, where pH-pM is equal to ...

Nano- and microsized zeolites as a perspective material for potentiometric biosensors creation Oleksandr O Soldatkin1,2*, Margaryta K Shelyakina1, Valentyna N Arkhypova1, Esin Soy3, Salih Kaan Kirdeciler3, Berna Ozansoy Kasap3, Florence Lagarde4, Nicole Jaffrezic-Renault4, Burcu Akata Kurç3,5, Alexei P Soldatkin1,2 and Sergei V Dzyadevych1,2 Abstract A number of potentiometric biosensors based on coimmobilization of enzymes with different types of zeolite on pH-ion-sensitive field-effect transistor (ISFET) have been developed. Their working characteristics have been determined and compared. It was shown that clinoptilolite and zeolite Beta polymorph A (BEA) are more promising for creating biosensors than zeolite A. Changing the concentration of zeolite ... Read more

New steps ahead for Greek zeolite – N. Lygeros New steps ahead for Greek zeolite – N. Lygeros Translated from the Greek by Athina Kehagias Within the context of the research licence for zeolite in Northern Evros, and more specifically in the Kokkala area near Petrota, we also had to address the issue of road construction, which is necessary to access the zeolite ore. This problem has now been resolved following a decision by the Secretary of Decentralised Administration for Macedonia-Thrace, as approval was granted for a Type C forest road for industrial mineral surveys of ore deposits, specifically zeolite. ...

Evaluation of the potential of zeolite as a soil conditioner for two Zambian soils – Makungwe, Mirriam. Degree: 2015, University of Zambia Highly weathered soils are characterised by poor nutrient and water-holding capacities, thereby limiting soil productivity. This study was conducted to investigate the potential for improving soil productivity by amending soils with zeolite to enhance moisture and cation retention capacities. Two experiments were carried out: i) In the first experiment, an ALISOL and an ACRISOL were each amended with zeolite to increase the cation exchange capacity (CEC) by 0, 25, 50, 75, 100 and 125 per cent. The mixtures ... Read more

The floods in Evros and zeolite – N. Lygeros The floods in Evros and zeolite – N. Lygeros The floods in Evros, with all the problems they have caused for farmers, do have one positive aspect: they have raised awareness even amongst our most indifferent citizens and the most incompetent politicians. Now everyone is complaining about the river and all the substances it carries downstream, which destroy the fields, not just the crops.  The point is that no one is proposing a specific solution to the problems that arise. Because, in fact, there is a solution, and more specifically in ... Read more

Due to its properties, zeolite has the ability to reduce odours in enclosed spaces within a short period of time.
