Hydrothermal synthesis and characterization of zeolite from Malaysia’s natural kaolin for adsorption of sodium ion (NA+) from seawater
Zeolite-A is widely known as aluminosilicate mineral that has been intensively used as an adsorbent in the adsorption process for desalination. Desalination is a technique to eliminate sodium ion and other minerals in the water. Because of the nature of seawater, which is very salty, the main …

EFFECTS OF FEEDING A COMBINATION OF SYNTHETIC ZEOLITE A AND 25 HYDROXYVITAMIN D3 DURING THE PREPARTUM PERIOD ON MINERAL METABOLISM AND LACTATION PERFORMANCE OF HOLSTEIN DAIRY COWS
… of two commercially validated products; zeolite, a dietary P binding aluminosilicate, and calcidiol, an intermediate vitamin D metabolite. The objectives of our study were to evaluate the effects of the combination of zeolite and calcidiol on mineral metabolism and lactation performance …

Synthesis, characterization and reactivity of transition metal containing zeolites
Transition metal containing zeolites (zeolite A and ZSM-5) were prepared by addition of various transition metal containing substrates to zeolite synthesis gels. Crystal growth data were recorded in order to determine the influence of the transition metal species on the rate of crystal growth. …

High throughput optical materials
… synthesis and characterisation of a variety of zeolites and aluminosilicates has been achieved using hydrothermal methods and solid state calcinations. The system using elemental aluminium, silica and sodium hydroxide solution as starting materials was explored using hydrothermal methods …

Gravimetric, neutron scattering and computational studies of the sorption and diffusion of gases in zeolites
Zeolites are a class of aluminosilicate materials with many important industrial applications as catalysts, ion exchange materials and sorbents. A novel dynamic Monte Carlo program has been written that allows both the kinetic and equilibrium properties of zeolitic systems such as CaNa zeolite A …

Development and optimization of zeolite synthesis route from natural koalin for adsorption of dyes
Synthesis of zeolite using kaolin as the main source of alumina and silica has been identified as a novel zeolite production process, which could reduce the cost of using the synthetic reagents and the high energy consumption. A low grade kaolin was used for studying the most suitable synthesis …

Heterogenous catalysis of inorganic reactions
Aluminosilicates, especially zeolite A, Surrey powder and alumina, are efficient and mild catalysts for ligand substitution reactions of inert Cr(" and Co(ffl) complexes. The reaction kinetics for the aquation of chromium(1H) chloride and chromium(llI) bromide hexahydrates, the anation reaction of …

Microwave synthesis and occlusion reactions of zeolites
… in this volume covers two distinct fields of zeolite chemistry. The first section of this thesis is dedicated to the synthesis of zeolites A (LTA), X (FAU), Y, (FAU) and rho (RHO) in a microwave oven. Results have demonstrated that when zeolitic gels are heated in a microwave oven they yield …

The purification of industrial wastewater to remove heavy metals and investigation into the use of zeolite as a remediation tool
Zeolites are well-known aluminosilicate minerals that have been widely used as adsorbents in separation, purification processes and environmental pollution control. Zeolites are used in various industrial applications due to their high cation-exchange ability, molecular sieve and cataltic …

Production of silver-loaded zeolites and investigation of their antimicrobial activity
The production of silver-loaded zeolites either by ion exchange method or by isomorphous substitution of silver ions into zeolites frameworks and their antimicrobial activity is presented. Silver-loaded zeolites produced by ion-exchange in this work include silver-exchanged zeolite X, …

Nucleation seeding in metakaolin geopolymers
… by adding silica, titania, synthesized zeolite A and zeolite X nanopowders as external seeds in MK-NaOH geopolymers. Isothermal calorimetry revealed that the addition of these nanoparticles accelerated the rate of heat evolution from metakaolin-sodium hydroxide (MK-NaOH) geopolymers at …
