The palygorskite (attapulgite) deposit in Georgia and Florida, United States, is over 60 km in length and may be one of the largest hormitic clay deposits in the world (Anon., 1978; Clarke, 1985). This deposit, which consists of 20-80% palygorskite (attapulgite) is thought to have resulted from marine sedimentation during the Miocene period (Harben
Ainsi un nid peut très bien absorber une première fois, puis devenir imperméable au cours du temps (étant saturé en eau, il ne peut plus rien absorber). Donc en plus de l'absorption, il serait intéressant d'étudier la propriété de "déshydratation" des matériaux (c'est-à-dire cette capacité à libérer l'eau qui a été absorbée).
SummaryNovel hydrogel nanocomposites, based on sepiolite, acrylic acid (AA), acrylamide (AM), and N,N'-methylenebisacrylamide (MBA), were synthesized by solution copolymerization.

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 compounds and …

Sepiolite and attapulgite have been found to be common, sometimes the major, clay minerals in calcareous lacustrine deposits on the southern High Plains in West Texas and eastern New Mexico. Deflation debris derived from the basins and calcareous soils developed in the debris and in the lacustrine deposits also often contain either or both minerals. Dolomite is the carbonate …
The passivation effect of the clays on Cd was ranked in sepiolite>attapulgite>bentonite, which could be further enhanced by adding phosphorus fertilizer.【Conclusion】Combing sepiolite (1%) and phosphorus fertilizer (0.04%) was most effective for in situ remediation of Cd-polluted Fluvo-aquic soil, with little effect on soil pH.

ATTAPULGITE C'est un minéral naturel aux caractéristiques similaires à celles de la sépiolite: très basse densité, grande porosité et grande surface spécifique. De même que pour la sépiolite, ces caractéristiques en font une argile absorbante. L'attapulgite de nos mines est encore plus légère que notre sépiolite.
