In average samples of three sandy-loamy acid Cambisols from a South Bohemian area labile organic matters were determined by the permangate method modified by the dichromate method, and the rate consta...
The European calcium carbonate and dolomite producers established their own representation at EU level through CCA-Europe, a founding member of the Industrial Minerals Association Europe (IMA-Europe).
Bovine serum albumin (BSA) Langmuir monolayer, as a model of biomineralization-associated proteins, was used to study its effect on regulated biomineralization of calcium carbonate. The effects of the...
Rare earth elements (REE), Sr, Ba, Fe, Mg, Ca, Na, and K concentrations in three kinds of living foraminiferal tests collected from Iriomote Island, Japan were measured in order to obtain some qualita...
Mn/Cr relative sensitivities for a synthetic calcite and a terrestrial olivine (San Carlos olivine) were measured using spot and rasterized modes with a NanoSIMS ion probe. Counting rates of 43Ca+, 52...
In this laboratory study, we monitored the buildup of biomass and concomitant shift in seawater carbonate chemistry over the course of a Trichodesmium bloom under different phosphorus (P) availabilit...
In this study, we investigated a novel method for fabrication of carbonate apatite block without ionic movement between precursor and solution by using precursor that includes all constituent ions of ...
In the summer of 2005, we sampled surface water and measured pH and total alkalinity (AT) underway aboard IB Oden along the Northwest Passage from Cape Farewell (South Greenland) to the Chukchi Sea. W...
A pot experiment was conducted at Soil Chemistry Section, Ayub Agricultural Research Institute, Faisalabad during 2001-2003. Five treatments i.e. 0, 3, 6, 9 and 12 percent CaCO concretion (CCC) ...
Sulfate particles play a key role in the air quality and the global climate, but the heterogeneous formation mechanism of sulfates on surfaces of atmospheric particles is not well established. Carbona...
Levels of coarse (PM10-2.5) and fine (PM2.5) particles were determined between February 2004 and January 2005 in the city of Beirut, Lebanon. While low PM mass concentrations were measured in the rai...
Quality precipitated calcium carbonate has much demand in various chemical and allied industries as filler, surface coating, whitening, adhesive etc. A study was carried out by modifying classical lim...
期刊信息 篇名 Dissolution Kintics of Calcium Carbonate Minerals in H2O-CO2 Solutions in Turbulent Flow:the role of the diffusion boundry layer and the solw reaction H2O+CO2←→H(+)HCO3 语种 英文 撰写或编译 作者 刘再华,W,Dr...
Korea has about 68 hundreds million tons of limestone's reserves. Still, high-Ca2+ limestone containing more than 52% calcium oxide makes up for about 12% only; hence the need for securing and effecti...
Limestone is abundant mineral that has occupied about 14% of the earth's crust and 20~30% of the sedimentary rock all over the world. As extensive distribution, limestone contains various minerals suc...
