Natural Clinoptilolite and Chabazite as Carriers for Antibacterial Agents: Cetylpyridinium Chloride (CPC) and Silver Abstract Natural clinoptilolite (Cli) and chabazite (Cha) were used as carriers for two types of antibacterial agents: cetylpyridinium chloride (CPC) and silver cations (Ag). CPC-zeolites, Ag-zeolites and CPC-Ag-zeolites were characterised using an energy-dispersive X-ray (EDX) analyser and Fourier transform infrared (FTIR)…

Study on the Effect of Adding Zeolite and Other Bio-Adsorbents on Enhancing the Quality of Palm-Based Vermicompost Abstract This research project focuses on the production of vermicompost from empty fruit bunches (EFB) mixed with cow dung, using an epigeic earthworm known as Eudrilus eugeniae. The vermicomposting process was carried out in a humid environment with…

The Study on Zeolite Column Adsorption of Groundwater Nitrate Abstract Using a zeolite column adsorption test to assess nitrate pollution in groundwater, the study investigated three different inlet flow rates for nitrate nitrogen removal, as well as the roles of nitrite nitrogen accumulation, zeolite adsorption of ammonia nitrogen and the influence of changes in pH…

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…

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…
