Characterization of lead sorption by the natural and Fe(III)-modified zeolite
(Elsevier, Amsterdam, 2013)
The influence of contact time, temperature and particle size on lead sorption by the natural and Fe(III)-modified zeolites was investigated. Characterization of the natural and Fe(III)-modified zeolite before and after ...
Isothermal sintering of barium-zinc-titanate ceramics
(Elsevier Sci Ltd, Oxford, 2011)
Mixtures of BaCO3-ZnO-TiO2 were mechanically activated using high-energy planetary ball mill during 20, 40 and 80 min. As the time of mechanical activation increased, the decrease in particle size was observed. The effect ...
Refractory coating based on cordierite for application in new evaporate pattern casting process
(Elsevier Sci Ltd, Oxford, 2011)
Standard raw materials, kaolin, talc, MgO, alumina, feldspar and sepiolite, were used in synthesis of four different cordierite type ceramics. Sintered cordierite was used as refractory filler in the ceramic coating for ...
Pb(II) removal from aqueous solution by Myriophyllum spicatum and its compost: equilibrium, kinetic and thermodynamic study
(Wiley, Hoboken, 2014)
BACKGROUND Lead is one of the frequent contaminants of industrial wastewater. Since it has been shown that aquatic plants can be used for the removal of heavy metals, herein Pb(II) biosorption by Myriophyllum spicatum and ...
Synthesis of nano-crystalline NiFe2O4 powders in subcritical and supercritical ethanol
(Elsevier Science Bv, Amsterdam, 2016)
Nano-crystalline nickel ferrite has a broad range of applications due to its favourable magnetic properties. Those characteristics can be significantly influenced by the synthesis pathway including methods conducted in the ...
Energy conversion in phosphate ore grain mixture activated via ultra-centrifugal mill
(Elsevier, Amsterdam, 2015)
The aim of this investigation was to establish the optimal processing parameters of the comminuted phosphate grain mixture mechanical treatment by monitoring and evaluating the activated product characteristics. An ...
Microbial solubilization of phosphorus from phosphate rock by iron-oxidizing Acidithiobacillus sp B2
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
Procedures for solubilization of phosphorus from insoluble phosphates by acidophilic autotrophs and heterotrophs are considered to be research subjects of great importance in sustainable soil management, and could become, ...
Hydrothermal conversion of grape pomace: Detailed characterization of obtained hydrochar and liquid phase
(Elsevier Science Bv, Amsterdam, 2016)
In this study, carbonization products of grape pomace (hydrochar and process water) have been thoroughly characterized in order to assess its fuel properties, physico-chemical composition and to optimize its production. ...
Alkali modified hydrochar of grape pomace as a perspective adsorbent of Pb2+ from aqueous solution
(Academic Press Ltd- Elsevier Science Ltd, London, 2016)
Hydrochar produced via hydrothermal carbonization of grape pomace was considered as novel sorbent of Pb2+ from aqueous solution. In order to enhance the adsorption capacity, hydrochar was chemically modified using 2 M KOH ...
Sintering, crystallization and foaming of La2O3 center dot SrO center dot 5B(2)O(3) glass powders: effect of the holding time
(Elsevier, Amsterdam, 2020)
Sintering, crystallization and foaming of nano glass powders with composition La2O3 center dot SrO center dot 5B(2)O(3) were studied by hot stage microscopy (HSM) and simultaneous thermal analysis (DTA-TG) under non-isothermal ...
