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 ...

zeolite: cultivating innovation – Nikos Lygeros Lecture by Nikos Lygeros on the topic: “zeolite: cultivating innovation”. Levidi-Philotechnikos Club.

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

Interview with Nikos Lygeros on zeolite on Radio Evros, 26 February 2015 Professor Nikos Lygeros speaks on Soula Kapetanidou’s programme about zeolite and how it can help address the issues facing the Hellenic Sugar Industry, flooding, genuine economic growth, and the fight against unemployment in the wider region of Thrace and Macedonia. www.radioevros.gr  

A new step forward for Greek zeolite – N. Lygeros | Zeolife.gr A new step for Greek zeolite – N. Lygeros As part of the exploration licence for zeolite in Northern Evros, and more specifically in the Kokkalo area, which is located near Petrota, there was also the issue of road construction, which is essential for access to the zeolite deposit. This problem has now also been resolved following the decision by the Secretary-General of the Decentralised Administration of Macedonia and Thrace, following the approval of the design for a Type C forest road for mineral exploration of industrial minerals, ...

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

Zeosoap Therapy – A student-run virtual business in Didymoteicho First-year pupils at Didymoteicho General Lyceum have set about creating and developing their own business as part of the educational programme ‘Virtual Enterprise’ implemented by the Youth Entrepreneurship Association (SEN) / Junior Achievement Greece. SEN/JA Greece is a non-profit organisation, a member of the global education and entrepreneurship organisation Junior Achievement Worldwide, and implements the organisation’s programmes in Greece. The ‘Virtual Enterprise’ educational programme, a group activity for sixth-form students, is based on the principle of ‘learning by doing’ and gives participants the opportunity to draw up a comprehensive business plan, set ...

Technical characteristics of zeolite utilisation – Nikos Lygeros | Zeolife.gr Technical characteristics of zeolite utilisation – Nikos Lygeros To avoid any comparison with any other mining operation, it is useful to be aware of the technical characteristics of zeolite mining in Thrace, as it is now widely recognised that all stakeholders are aware that the project must go ahead, and indeed with vigour. The operation of the zeolite quarry will, of course, be open-cast, as access is direct and will be carried out using the method of straight, successive open-cut benches, which is the most widely recognised. The rock is ... Read more

The Evros floods and zeolite – N. Lygeros The Evros floods and zeolite – N. Lygeros The Evros floods, with all the problems they cause for farmers, do have the merit of raising awareness even amongst our most indifferent citizens and our most incompetent politicians. Now everyone is up in arms against the river and all the substances it carries, which are destroying not only the crops but all the fields as well. The problem is that no one is proposing a specific solution to the problems that arise. Because, in fact, a solution does exist – and indeed right ... 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
