AbstractPoly(vinyl alcohol) (PVA)/attapulgite (AT) nanocomposite fibers have been prepared by wet spinning. The morphology and mechanical properties of the modified PVA fibers have been characterized with transmission electron microscopy, scanning electron microscopy (SEM), differential scanning calorimetry (DSC), birefringence measurements, and ...

New data on Sepiolite and Attapulgite
Clays and clay minerals (National Conference on Clays and Clay Minerals), 1956AbstractHydrothermal studies have failed to yield synthetic attapulgite or sepiolites in the system MgO-Al2O3-SiO2-H2O. However, the natural minerals can be decomposed to yield mont-morillonoids by mild hydrothermal treatment as low as 200°C and probably as low as 100°C. These data indicate that they are metastable and probably could not have formed at

Oxidative degradation of hydrocortisone in presence of attapulgite
Journal of Pharmaceutical Sciences, 1980Degradation of hydrocortisone in attapulgite suspensions was monitored by high-pressure liquid chromatography and UV spectrophotometry. The rate of oxidative degration of hydrocortisone was accelerated significantly in the presence of attapulgite. In addition, degradation appeared to be composed of two apparent first-order reactions rather than the ...

[The adsorption on attapulgite and cross-linked agar beads entrapped attapulgite(CAA)].
Sheng wu yi xue gong cheng xue za zhi = Journal of biomedical engineering = Shengwu yixue gongchengxue zazhi, 2002The adsorption of four drugs with certain toxicity, i.e. chlorpromazine, quinidine, diazepam and phenobarbital on attapulgite and Cross-linked Agar Beads Entrapped Attapulgite(CAA) was determined in this study. The results revealed that attapulgite possessed high adsorption for the cation drugs(chlorpromazine and quinidine), moderate adsorption for ...

Assessment of the Fibrogenicity of Attapulgite
1990Attapulgite, also named palygorskite, is a fibrous clay mineral extracted from the soil in several countries, mainly USA, France, Spain, India and USSR for a world consumption in excess of one million tons per year. The material is an hydrated magnesium aluminum silicate with unique chain structure that gives it unusual colloidal and sorptive ...
