Solubilities of corundum, wollastonite and quartz in H2O–NaCl solutions at 800 C and 10 kbar: Interaction of simple minerals with brines at high pressure and temperature
Solubilities of corundum (Al2O3) and wollastonite (CaSiO3) were measured in H2O–NaCl solutions at 800 C and 10 kbar and NaCl concentrations up to halite saturation by weight-loss methods. Additional data on quartz solubility at a single NaCl concentration were obtained as a supplement to previous work. Single crystals of synthetic corundum, natural wollastonite or natural quartz were equilibrat...
متن کاملRole of saline fluids in deep-crustal and upper-mantle metasomatism: insights from experimental studies
Chloride-rich brines are increasingly recognized as playing an important role in high pressure and temperature metamorphic and magmatic systems. The origins of these saline multicomponent fluids are debated, but experimental evidence suggests that regardless of their origin they must be important agents of rock alteration and mass transfer wherever they occur. Studies of the solubility of quart...
متن کاملPetrochemical wastewater treatment by modified electro-Fenton process with nano iron particles
Petrochemical manufacturing wastewaters often contain a high concentration of biodegradable com-pounds that possess either toxicity or activity inhibition to the biological unit. In this paper, COD removal from Petrochemical wastewaters by electro-Fenton process was studied. The effect of operating conditions such as reaction time, current density, pH, H2O2/Fe2+ molar ratio, and H2O2 of petroch...
متن کاملIon association in concentrated NaCI brines from ambient to supercritical conditions: results from classical molecular dynamics simulations
Highly concentrated NaCl brines are important geothermal fluids; chloride complexation of metals in such brines increases the solubility of minerals and plays a fundamental role in the genesis of hydrothermal ore deposits. There is experimental evidence that the molecular nature of the NaCl–water system changes over the pressure–temperature range of the Earth’s crust. A transition of concentrat...
متن کاملGeneration of *OH initiated by interaction of Fe2+ and Cu+ with dioxygen; comparison with the Fenton chemistry.
UNLABELLED Iron and copper toxicity has been presumed to involve the formation of hydroxyl radical (*OH) from H2O2 in the Fenton reaction. The aim of this study was to verify that Fe2+-O2 and Cu+-O2 chemistry is capable of generating *OH in the quasi physiological environment of Krebs-Henseleit buffer (KH), and to compare the ability of the Fe2+-O2 system and of the Fenton system (Fe2+ + H2O2) ...
