Retaining nutrients and water in agricultural soils brings about higher crop yields and prevents pollution of water courses. Among different solutions, zeolites, which are environmental friendly, ubiquitous, and inexpensive, have been extensively employed in ... Διαβάστε περισσότερα

C. Sangeetha* and P. Baskar1, Department of Agronomy, Tamil Nadu Agricultural University, Coimbatore – 641 003, India. Received: 10-09-2015 Accepted: 25-02-2016 DOI:10.18805/ar.v0iof.9627 ABSTRACT In many parts of the world food security is being affected due to declining quality and/or quantity of the soil resource base and climate change. In this context, farming with zeolites has drawn attention. Zeolites are natural aluminosilicates present in rocks different part of the world. Use of zeolite has gained a momentum in the recent past owing to multitude of benefits accured from them. Zeolites are useful in agriculture because of their large porosity, cation exchange capacity and selectivity ... Διαβάστε περισσότερα

Bekturov Institute of Chemical Sciences, Ministry of Education and Science, Kazakhstan Introduction Intensive studies of natural and synthetic zeolites properties are being held from the middle of 60-70-ies. Among the various examples of zeolites application it is sufficient to mention emission and purification of normal paraffin hydrocarbons, catalytic reactions of hydrocarbons, extraction of radioactive isotopes, obtaining carriers for catalysts, release of enzymes and removal of impurities polluting the atmosphere [1-3]. The interest of researchers towards such alumosilicates ... Διαβάστε περισσότερα

In vitro σύγκριση του Ζεόλιθου (κλινοπτιλόλιθος) και του ενεργού άνθρακα ως απορροφητικά αμμωνίας στην ιχθυοκαλλιέργεια – In vitro Comparison of Zeolite (Clinoptilolite) and Activated Carbon as Ammonia Absorbants in Fish Culture H. Emadi, J.E. Nezhad and H. Pourbagher Abstract Conditioned activated carbon was compared with zeolite (clinoptilolite) at different salinities, Total Ammonia Nitrogen (TAN) and times. The dosages of both materials were the same ie. 10 ppt. Different salinities from 0 to 30 ppt were prepared in 24 three-liter plastic buckets. One, 3 and 5 ppm TAN were added to the buckets. TAN absorption trend was monitored every 4 hours ... Διαβάστε περισσότερα

Daniel, Claudia; Dierauer, Hansueli and Clerc, Maurice (2013) The potential of silicate rock dust to control pollen beetles (Meligethes spp.). IOBC wprs Bulletin, 96, pp. 47-55. Summary In organic agriculture, treatments with rock dusts for soil amendment, disease prevention, or insect control have a long tradition. Clinoptilolite (a naturally occurring zeolite) was tested against pollen beetle Meligethes spp. in organic and IPM oilseed rape fields in order to find a control strategy compatible with the guidelines for organic and IPM agriculture in Switzerland. Dust and spray applications were evaluated in several large-scale field trials from 2008 to 2011. Dust applications ... Διαβάστε περισσότερα

Mark W. Ackley, Salil U. Rege, Himanshu Saxena Praxair, Inc., 175 East Park Drive, Tonawanda, NY 14151, USA Received 22 July 2002; received in revised form 21 October 2002; accepted 22 October 2002 Abstract There are many natural zeolites of which a small number including clinoptilolite, chabazite, mordenite, erionite, ferrierite and phillipsite offer the greatest promise for gas separation. Patents and other literature have been surveyed to identify the bulk separation and purification processes for which these zeolites have potential. The abundance and low raw material cost of natural zeolites have rarely offset such disadvantages as variable composition, low purity ... Διαβάστε περισσότερα

More than 85 percent of all wood-based materials are manufactured using adhesives containing formaldehyde. Increasingly strict regulations concerning these emissions have been creating major challenges for adhesive manufacturers and the wood-based product industry since the 1970s. The primary objective of the project was to considerably reduce the formaldehyde emissions from wood-based products by adding small amounts of absorbers on the basis of zeolites with simultaneous catalytic effect. Modifizierung einer Zeolithoberfläche mit 3-Aminopropyltriethoxysilan (nach Liu et al. 1997). Adhesives containing formaldehyde are, compared to other suitable types of adhesive, extremely economically-priced and are therefore indispensible for the wood-based materials industry in ...
