چکیده

The haemolytic potential of attapulgite (Senegal) has been investigated. When the particles were pretreated with dipalmitoyl phosphatidylcholine (DPPC) or with bovine serum albumin (BSA) at a concentration that would obtain maximum coverage of the particles by adsorption, a change in haemolysis was observed. The results indicate that haemolysis is strongly dependent on the surface state of the particles.

Potential health risks from the use of fibrous mineral absorption granulates.

Attapulgite (palygorskite) and sepiolite are fibrous clay minerals used commercially as components in a wide variety of products including oil and grease adsorbents, carriers for pharmaceuticals, cosmetics, and pesticides. They are also components of drilling muds and animal litter and they are used as paint thickeners. The current annual worldwide production of these minerals exceeds one milli...

Adsorption Mechanism of Toxic Metal Ions by Clay (attapulgite)

A series of adsorption tests were conducted to analyze the sorption capacity of attapulgite. Ions such as cobalt, nickel, lead and cadmium were adsorbed from waste solutions onto attapulgite surface. Adsorption depletion tests were performed as a function of solid to liquid ratio, conditioning time, heavy metal ion concentration, and pH to identify the mode and extent of interactions in the sys...

Evaluation of the Potential of Using an Omani Attapulgite as a Sorbent in Treatment of Contaminated Water

The goal of this study is to investigate and develop a cost-effective procedure for the treatment of contaminated water by sorption technology using an Omani clay mineral. Attapulgite (Palygorskite) is a clay mineral that exists in the Sultanate of Oman in huge reserves in two deposits in the southern part of Oman. In this paper, we present our first findings about this important clay in the re...

Characterisation of palygorskite specimens from different geological locales for health hazard evaluation.

Palygorskite, a fibrous clay mineral, is being used as a substitute for asbestos in some applications. Nine specimens obtained from different geological locales were studied for mineral purity, elemental composition, fibre size distribution, and surface binding characteristics. The membranolytic activity of each was determined using a human erythrocyte model. The membranolytic behaviour and sur...

The filtration behaviour of some clay–water dispersions was studied. Two Spanish fibrous phyllosilicates (sepiolite from Vicálvaro and palygorskite from Turón) and a commercial bentonite (Bentopharm©, UK) with similar sizes and different morphologies (fibrous and/or laminar) were selected as model clays. Sepiolite from Vicálvaro is an almost pure fibrous sample, Bentopharm© presents a high amou...
