Attapulgite-pesticide interactions

1981
As most pesticides are either insoluble or only slightly soluble in water and must be applied in relatively small amounts over large areas, they are formulated in such a way that a highly concentrated organic chemical can be put into a convenient-to-use and effective form for field use by blending it with additives and inert carriers.

Electrochemical Properties of Na–Attapulgite

Journal of Colloid and Interface Science, 1996
Abstract Analytical surface charge (σ a ), electrophoretic, and physicochemical properties of an homoionic form of Na–attapulgite show some similarity with those exhibited by homoionic sodium forms of the platy clay minerals kaolinite and illite. Both electrophoretic mobility ( u e ) and analytic or titratable surface charge show dependency on pH ...

A RANDOM INTERGROWTH OF SEPIOLITE AND ATTAPULGITE

Clays and clay minerals (National Conference on Clays and Clay Minerals), 1960
AbstractThe smectic clays from Cabo de Gata region, Almeria, Spain, are composed mainly of montmorillonite, but they contain appreciable quantities of fibrous clay minerals, some of which are of the palygorskite type. However, there also is a mineral that has properties intermediate between those of palygorskite and sepiolite. Its structure seems to be

Fibrillar Attapulgite–Rubber Nanocomposites

2016
Rubber, as a special polymer material with high elasticity at room temperature, has been widely used in industries. However, rubber has to be reinforced by using nanofillers to meet the needs of industrial applications because of its low mechanical strength.

The lung biological activity of american attapulgite

Environmental Research, 1987
Attapulgite is a fibrous mineral industrially consumed at the rate of over a million tons per year but the biological activity of the material is not fully known. To evaluate the in vivo toxicity of the fibrous material, we exposed the tracheal lobe of 16 sheep to a single exposure of either 100 ml saline, 100 mg UICC asbestos fibers in 100 ml saline ...

Comparative Studies of Activated Carbon-Attapulgite and Zeolite-Attapulgite Composite Adsorbent on Congo Red Adsorption

Applied Mechanics and Materials, 2010
This study investigated the adsorption of congo red by activated carbon-attapulgite composite adsorbent (ACA) and zeolite-attapulgite composite adsorbent (ZA) from aqueous solution. All of these two adsorbents have mesopores and macropores structure different from general activated carbon adsorbent with micropores distribution through analysis of ...

Ternary Polypropylene/Polyolefin Elastomer/Attapulgite Composites

Advanced Materials Research, 2006
Modification of polypropylene (PP) by the addition of polyolefin elastomer (POE) and attapulgite (AT) has been investigated. The result have shown that the addition of POE and AT gave PP excellent mechanical properties of improved impact strength and comparable stiffness.

Some Notes on Attapulgite

Clay Minerals, 1950
As both attapulgite clays and some montmorillonite clays are termed “fuller's earths” in the literature, a comparison is made between the physical properties of the two groups of material, with special reference to those which are important commercially.

Attapulgite: Properties and Uses

Clays and clay minerals (National Conference on Clays and Clay Minerals), 1961
AbstractThe clay mineral attapulgite derives its non-swelling needle-like morphology from its three-dimensional crystal structure. The shape and size of the needles result in unique colloidal properties, especially resistance to high concentrations of electrolytes, and give high surface area, high porosity particles when thermally activated.

Biological effects of attapulgite.

IARC scientific publications, 1981
Some clay minerals occur naturally in a fibrous or lath-like crystal state as attapulgite and sepiolite. Because of their sorptive and colloidal properties, attapulgite and sepiolite have numerous industrial applications, mainly as additives in oil-drilling muds, in chemical fertilizers, pesticides, paints, adhesive products, bleaching agents, cosmetic
