Book: Zeolites: Science and Technology December 16th, 2009
PREFACE
Zeolites have been the focus of intensive activity and growth in applications over the past 25 years in ion exchange, in adsorption and in catalytic process technology. Beginning with the synthetic zeolites A,X and Y, continuing into the emerging ZSM series, and including selected natural zeolites, applications span the range from large-scale purification and separation to such major petroleum and petrochemical processes as catalytic cracking and aromatics alkylation. more…
Natural Liquid Zeolite Detox September 23rd, 2009
Tree of Life Rejuvenation Center, Dr. Gabriel Cousens, 11/13/2007
This summary details a major breakthrough in detoxifying the human body of the carcinogens, heavy metals, viruses, bacteria, fungi, and overall acid conditions that promote and cause disease. Some 70,000 chemicals are being dumped into our environment, 65,000 of which are potentially hazardous to our health. We live in a virtual sea of pollutants, and carry many of these toxins within us. They can be found even in unborn children. A 2004 study by the Environmental Working Group identified 287 industrial chemicals in babies’ umbilical-cord blood, including 180 known to cause cancer and 217 that are toxic to the brain and nervous system. more…

Natural Cellular Defense September 16th, 2009
Key Points
Natural Cellular Defense is derived from a naturally-occurring mineral zeolite. Zeolites are considered 100 percent safe and non-toxic by the FDA. Natural Cellular Defense and its constituent zeolite have been shown to have the following functions:
• Retains the natural zeolite property of reducing cancer risk
• Acts as a potent anti-oxidant
• May aid in balancing bodily pH levels
• Acts to chelate and remove heavy metals from the system
• Reduces the incidence of diarrhea
• Improves nutrient absorption in the digestive tract
• Acts to balance digestive pH, thus reducing acid reflux
• Acts to stabilize immune system function (immunomodulatory)
• Acts as a broad spectrum anti-viral agent
Study: Zeolite Minerals for Uptake of Mercury Solutes September 8th, 2009
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. The effect of mercury concentration on the Kd response is shown over an environmentally appropriate concentration range of 0.1–5 ppm inorganic and organometallic Hg using a batch factor of 100 ml g–1 and 20 h equilibration. Analcime and a Na-chabazite displayed the greatest methylmercury uptakes (Kd values at 1.5 ppm of 4023 and 3456, respectively), with mordenite as the smallest at 578. All uptake responses were greater for methylmercury than for the inorganic mercuric nitrate solutions, suggesting a distinctive sensitivity of zeolites to reaction with different types of solute species. It is likely that this sensitivity is attributable to the precise nature of the resultant Hg-zeolite bonds. Additionally, both the Si-Al ratio and the Na content of the initial natural zeolite samples are shown to influence the Kd responses, with positive correlations between Kd and Na content for all zeolites excluding mordenite.
Study: Desalination Using Zeolite Membranes September 8th, 2009
Introduction:
- The new synthetic Zeolite membrane successfully tested by Dr. Dong’s PRRC/NM Tech.
- The Zeolite membrane has ~ 90% of an 80,000 ppm produced water.
- It is an inorganic membrane.
– High flux
– High thermal and chemical stability
– Regeneration capability
– Perhaps, low pretreatment cost

Study: Biosorption of Chromium Using a Bacterial Biofilm with Zeolite September 2nd, 2009
Two mini-columns partially filled with granular activated carbon (GAC) and/or a natural zeolite, covered by a bacterial biofilm of Arthrobacter viscosus, were used in a continuous flow system to remove Cr (VI) from solutions with initial concentration of 70mg/l and a working pH ranging between 4.5 and 5.5. Three different set-up’s were used: two columns in series filled GAC covered with a biofilm, two columns in series filled with zeolite covered with a biofilm and a column filled with GAC followed by another column filled with zeolite, both supports covered with biofilm. Comparatively, the biosorption system supported on GAC reaches similar removal values, 19%, as the one supported on the zeolite, 18%, but when these two beds are used in combination better performances are reached, i.e. 42% removal. The maximum uptake values ranged from 0.57mg(Cr)/g(Support) to 3.58mg(Cr)/g(Support). The interactions between metal ions and functional groups on the cell wall surface of the biomass were confirmed by FTIR. GAC was regenerated with steam draughting and reused twice. The first regeneration caused a decrease in the removal capacity of 38% and the second regeneration caused a total decrease in the removal capacity of 76%.
Study: Zeolites in Ethylene Removal August 13th, 2009
Zeolite impregnated films, paper liners, and packing foam blocks are being sold or are in commercial development to market to the horticulture industry. Among the benefits promoted is the removal of ethylene from the airspace surrounding and external to packed commodities. We have evaluated several zeolite-based products or prototypes being targeted to the floriculture industry for the protection of ethylene-sensitive potted plants and cutflowers during short-term storage, transportation and distribution.
Conclusion: Potassium permanganate-based product, Ethylene Control, could be shown to remove ethylene from the enclosed air space.
Study: Zeolite on Seedling Production August 13th, 2009
In agriculture, zeolite is used as a soil treatment. In this study, data was collected on the physical quality of the substrate, micronutrient solubility in the substrate, and micronutrient content of the plants.
Conclusions:
- In this experiment, zeolite has improved seedling growth.
- This beneficial effect of zeolite was more pronounced in the substrates without compost.
- The source of nitrogen fertilization had no influence on plant growth.
- Shoot dry weight showed the biggest differences.
Study: The Removal of Heavy Metals August 13th, 2009
Many toxic heavy metals have been discharged into the environment as industrial wastes, causing serious soil and water pollution.
In this study, the adsorption behavior of natural (clinoptilolite) zeolites with respect to Co2+, Cu2+, Zn2+, and Mn2+ has been studied in order to consider its application to purity metal finishing wastewaters.
Conclusion: These results show that natural zeolites hold great potential to remove cationic heavy metal species from industrial wastewater. This naturally occurring material provides a substitute for the use of activated carbon as adsorbent due to its availability and its low cost.
