The flammability of cotton fabric was improved by treated with the composite containing attapulgite(ATP). To achieve this aim, the poly(acrylic acid)/attapulgite nanocomposite (PAA/ATP) was successfully synthesized by the free radical polymerization of acrylic acid and the 3-methacryloxypropyltr...

Diclofenac (DCF) is a common anti-inflammatory drug. In this work, we have developed two new modified electrodes based on attapulgite clay mineral for the determination of DCF. The first one is made of an amino-functionalized attapulgite modified glassy carbon electrode (GCE/Amino-AT) issued fro...

First principles calculations are carried out to study the occupation properties of heavy metals (Cr, Mn, Ni, Cu, Zn, As, Cd, Sb, Hg and Pb) in attapulgite. The stability of attapulgite with different distributions of Al and Mg ions and the influence of aluminum contents was evaluated by calcula...

Graphene oxide (GO) based membranes are widely adopted in molecular separation based on size exclusion effect by stacked GO sheets. Both high flux and efficient rejection of GO-based membranes for long-term operation are highly expected for practical applications. Here, an attapulgite (ATP) nano...

The comprehensive sources of particulate matter (PM) require air purification materials to possess both high filtration efficiencies and low air resistances in an effort to provide healthcare. However, the assembly of multiple-layered filters with different functions leads to high pressure drop ...

As hydrated magnesium-aluminum-silicate crystals, attapulgite and HNO3/NaOH pretreated attapulgite were used as support to prepare nickel-based catalysts via ultrasonic-assisted impregnation method. The as-prepared catalysts were employed in the biomass derived gas (especially CO2 and CH4) refor...

Clay minerals are widely used as backfill and buffer materials, and it is known that clay colloids derived from an engineered barrier system may affect the migration behaviors of radionuclides. Based on a study of the stability of attapulgite colloids and the sorption behavior of uranium on atta...

The jade mineral nephrite has been examined by electron diffraction and high resolution lattice imaging. Planar defects parallel to (010) were observed. It is shown that these are Wadsley defects, consisting of multiple-chain lamellae in place of the double-chain amphibole host structure. Exampl...

Mineralogical analyses of nephrite jade artifacts have been used to identify likely causes of alterations in which some specimens exhibit raised relief above the original polished surfaces. In all of the specimens examined, the raised areas consist of either large diopside ± large tremolite cry...

Nephrite jade occurs in three terranes (Dun Mountain–Maitai, Caples and Torlesse) in New Zealand, where it is associated with ultramafic and ophiolitic rocks in narrow metasomatic reaction zones at the margins of serpentinite (having harzburgite/gabbro/dolerite precursors) with silicic metasedi...

The most highly valued placer nephrite deposits in the world occur in the Yurungkash and Karakash Rivers (also known as the White and Black Jade Rivers) in Hetian, Xinjiang, Northwest China. However, the ages of these deposits and the geological environment in which they formed are not known, an...

Glow discharge mass spectrometry (GD-MS) was applied to study the nephrite minerals formed by different metallogenic mechanisms and geological environments from deposits in China, Canada, New Zealand and Russia. The GD-MS analysis and multivariate statistic analysis results indicated that two ty...

The Yurungkash and Karakash rivers, also known respectively as the White Jade and Black Jade rivers, located in Hetian, Xinjiang Province, Northwest China, are the two main sources in China of white, green, and black placer nephrite, with a long history (~ 5000 years) of exploration and mining. ...

The Hetian nephrite deposit is one of the largest nephrite deposits worldwide. Located within the Hetian deposit, Xinjiang, Northwest China, the Alamas ore body occurs as veins on the contact between the Late Variscan granodiorite and Precambrian dolomitic marble. Petrographic studies and electr...

External-beam PIXE was used to determine the major, minor and trace elements of 45 nephrite minerals from 14 different deposits, including China and other countries. Depending on the R∗ value (mole percent of Mg2+/(Mg2+ + Fe2+(3+))) and content of Cr, Co and Ni, two types of nephrite minerals fr...

The Liaoning Province in the northeastern part of the North China Craton (NCC) hosts several tremolite jade (nephrite) deposits. Here we investigate the Sangpiyu tremolite jade deposit where the relationship between abundant graphite inclusions within the jade remains enigmatic. We employ petrog...

Concurrent with the increase in nephrite mining in recent years, many new nephrite deposits have been discovered worldwide. However, studies of these new deposits remain limited. To address this knowledge gap, the objective of this study was to systematically investigate the nephrite deposit in ...

The Cs ion was partially adsorbed (4.0% in all of the alkali cation sites) on natural mordenite as a simulated decontamination, then heat-treated to immobilize the Cs in the decomposed zeolite. Although the mordenite phase was maintained for the samples even heated at 800 °C, a glassy amorphous...

The purpose of this research work is to prepare and assess the catalytic performance of platinum (Pt) dealuminated mordenite for the of n-hexane, n-pentane and light naphtha isomerization. The Pt dealuminated mordenite was prepared by dealumination of commercial mordenite catalyst by refluxing u...

Direct hydrothermal synthesis of mordenite without the addition of both seed and organic template is reported in this work. The role of inorganic cations in the crystal purity and directing the mordenite structure were studied. It was observed that higher Si/Al ratio requires higher alkalinity o...
