AAS, XRPD, SEM/EDS, and FTIR characterization of Zn2+ retention by calcite, calcite–kaolinite, and calcite–clinoptilolite minerals
(Elsevier, 2005-04-08)In this study, the sorption behavior of Zn2+ on calcite, kaolinite, and clinoptilolite, in addition to mixtures of calcite with kaolinite and clinoptilolite, was investigated at various loadings and mixture compositions ... -
Determination of CaCO 3 and SiO 2 content in the binders of historic lime mortars
(Springer, 2012-06)The binders of historic mortars composed of small grain sized silica (SiO 2) and carbonated lime (CaCO 3) are considered as the main part that give hydraulic character and high strength to the mortar. In this study, FTIR, ... -
Effect of reaction conditions and organic additives on the morphologies of synthetic calcium carbonates
(İzmir Institute of Technology, 2006)In this study, the effects of experimental conditions on the facile morphosynthesis of CaCO3 were investigated. The analyzed conditions included the pH, concentration, mixing and aging temperature, and aging time. After ... -
Morphosynthesis of CaCO3 at different reaction temperatures and the effects of PDDA, CTAB, and EDTA on the particle morphology and polymorph stability
(Elsevier, 2007-09)Facile precipitation of CaCO3 was performed using aqueous solutions of CaCl2 with Na2CO3 over a wide range of mixing and aging temperatures. The precipitation process was then repeated in the presence of PDDA, CTAB, and ... -
Nano calcite (CaCO3) production in semi-batch bubble reactor
(Izmir Institute of Technology, 2013)Calcium carbonate (CaCO3) has been widely used as filling material in many industries due to its low cost and enhancement in some of the physical properties of the composite materials. The main purpose of this study was ... -

Production of nano calcite in large scale
(Izmir Institute of Technology, 2013)Calcium carbonate (CaCO3) has been used extensively as filling material in various industries in order to improve some mechanical properties of the composite materials and to reduce the product costs. There are mainly two ... -
Retention of aqueous Ba2+ ions by calcite and aragonite over a wide range of concentrations: Characterization of the uptake capacity, and kinetics of sorption and precipitate formation
(The Geochemical Society of Japan, 2007)The uptake of aqueous Ba2+, ions by abiogenic calcite and aragonite was studied over a wide range of concentration; 1.0 × 101, 5.0 × 101, 1.0 × 102 5.0 × 102, 1.0 × 103, 5.0 × 104, and 1.0 × 104 mg/L. The uptake process ... -
Study of the scavenging behavior and structural changes accompanying the interaction of aqueous Pb2+ and Sr2+ ions with calcite
(The Geochemical Society of Japan, 2005)The uptake of Pb2+ and Sr2+ ions from aqueous solutions by calcite was studied at various initial concentrations and pH conditions using the batch method under ambient conditions. XRPD, SEM/ EDS, AAS/AES, and DRIFT techniques ...
