Water pollution, particularly from heavy metals, poses a significant threat to global health, necessitating efficient and environmentally friendly removal methods. This study introduces novel zeolite-based adsorbents, specifically alkali-activated foamed zeolite (AAFZ), for the effective adsorption of Cu(II) Ni(II) ions aqueous solutions. The adsorbents’ capabilities were comprehensively characterized through kinetic isotherm analyses. Alkaline activation induced changes in chemical...
Elevated concentrations of heavy metals in natural waters can cause significant ecological problems. It is therefore essential to ensure their removal from any water discharged into the environment immediately, especially case an accident, where there a risk releasing large quantities or high concentrations. The aim this paper test newly developed adsorbent for aqueous solutions-in particular, it very fast adsorption, and thus efficiency, during clean-ups. alkali-activated foamed zeolite was...
Natural zeolites are crystalline hydrated alkali metal and alkaline earth aluminosilicates with unique ion-exchange sorption properties. The exceptional structure of pores gives natural several application possibilities, especially for water treatment construction. For a wider use zeolites, such as catalysis, properties—especially chemical, textural, mechanical—need to be modified. In this study, the basic zeolite foam was synthesized by activation an activator (KOH + Na2SiO3) foamed...
Aldol condensation reaction is usually catalysed using homogeneous catalysts. However, the heterogeneous catalysis offers interesting advantages and possibility of cleaner biofuels production. Nowadays, one most used kinds catalysts are hydrotalcites, which belong to a group layered double hydroxides. This paper describes aldol cyclohexanone (CH) furfural (F) Mg/Al mixed oxides rehydrated in order compare catalyst activity after calcination rehydration, as well its regeneration. The were...
This study focused on natural materials such as clinoptilolite (CLI), metakaolin (MK), marlstone (MRL) and phonolite (PH). Clinoptilolite is one of the most known common minerals (zeolites) with a unique porous structure, calcined kaolin clay, sedimentary rock an igneous composed alkali feldspar other minerals. These are mainly used in building industry (additions for concrete mixtures, production paving, gravels) or water purification, but modification their chemical, textural mechanical...
In this work, we studied the effect of alkali-activated zeolite foams modifications on properties and catalytic activity cobalt phases in process decomposition N2O. The foam supports were prepared by alkali activation natural followed acid leaching ion exchange. catalysts synthesised a different deposition technique (direct exchange (DIE) incipient wetness impregnation (IWI) method foams. For comparison, selected all compared tests pellet form as crushed to determine internal diffusion....
according to the basic thesis of phenomenology natural world exists in phenomenal site which is reflected knowledge we know from elsewhere, our case science, not itself.We do live world, however, but created have ideas and beliefs about nature world.We see through this belief (husserl 1996), concept.2 cognitive anthropology examines relationship between society culture, exploring how people perceive objects events that make up understanding influences their behavior (d'andrade 1995).
