Two industrial wastes (IW1 and IW2) were investigated as potential sorbents to retain cadmium lead from contaminated water. The sorption experiments have been conducted through lab-engineered cartridge filtration system in order get close possible processes. effectiveness of IW1 IW2 compared that activated charcoal Norit® (AC), the best-known matrix for its excellent retention capacity. isother...

Lead (Pb) solubility is commonly limited by dissolution–precipitation reactions of secondary mineral phases in contaminated soils and water. In the research described here, Pb free Pb2+ ion activities were measured following precipitation minerals from aqueous solutions containing sulfate or carbonate a 1:5 mole ratio absence presence phosphate over pH range 4.0–9.0. Using X-ray diffraction Fou...

The new mineral plumbophyllite, Pb2Si4O10·H2O, is orthorhombic with space group Pbcn and cell parameters a = 13.2083(4), b = 9.7832(3), c = 8.6545(2) Å, V = 1118.33(5) Å3, and Z = 4. It occurs as colorless to pale blue prismatic crystals to 3 mm, with wedge-shaped terminations at the Blue Bell claims, about 11 km west of Baker, San Bernardino County, California. It is found in narrow veins in a...

Abstract Carbonate minerals play a dominant role in the deep carbon cycle. Determining high-pressure and high-temperature vibrational properties of carbonates is essential to understand their anharmonicity thermodynamic under crustal upper mantle conditions. Building on our previous study aragonite, calcite (both CaCO3 polymorphs), dolomite [CaMg(CO3)2], magnesite (MgCO3), rhodochrosite (MnCO3)...

Lead contamination at shooting range soils is of great environmental concern. This study focused on weathering of lead bullets and its effect on the environment at five outdoor shooting ranges in Florida, USA. Soil, plant, and water samples were collected from the ranges and analyzed for total Pb and/or toxicity characteristic leaching procedure (TCLP) Pb. Selected bullet and berm soil samples ...

EXAFS measurements in the corrosion deposits were performed on Bell Labs-UIUC beamline X16C at the NSLS at Brookhaven National Laboratory in grazing incidence fluorescence mode at room temperature. EXAFS in the reference Cu and Pb metal foils, malachite, cerussite and hydrocerussite were measured in transmission. Sagittally focused second crystal in the double crystal Si (111) monochromator all...

Gardaneshir Pb–Zn deposit is hosted by dolomitic carbonates which is located in the SW Ardestan, central Iran. Ore body is stratabound type in this deposit. Primary ores in this type are composed of sphalerite, galena, barite and quartz with massive, banded, veined and disseminated structures. Evaluation of ore-grade at the Gardaneshir Pb-Zn deposit, based on chemical analysis which indicates a...
