Low-Temperature Pyrolysis of Crocidolite and Amosite using Calcium Salts as a Flux

Asbestos (chrysotile, Amosite, Crocidolite, Tremolite, Actinolite, and Anthophyllite)

Asbestos is the generic commercial designation for a group of naturally occurring mineral silicate fibres of the serpentine and amphibole series. These include the serpentine mineral chrysotile (also known as ‘white asbestos’), and the five amphibole minerals – actinolite, amosite (also known as ‘brown asbestos’), anthophyllite, crocidolite (also known as ‘blue asbestos’), and tremolite (IARC, ...

Removal of Alizarin Red Dye Using Calcium Hydroxide as a Low-cost Adsorbent

Calcium ions have very strong affinity and binds effectively to alizarin red dye during staining of biomaterials. This promotes us to choose calcium hydroxide as a low cost adsorbent for the removal of alizarin red dye. Various parameters such as pH, concentration, dose of adsorbent, time, and temperature have been investigated. In addition, enthalpy, entropy, free energy and activation energy ...

Calcium and Calcium Salts.

Calcium is the most abundant mineral in the body. Bones and teeth contain approx. 99% of calcium. Calcium exists in both plant and animal foods. The best source of calcium is milk. Indian Council of Medical Research (ICMR) recommends 600-800 mg/day of calcium which increases to 1200 mg/day in pregnant and lactating mothers. Inadequate calcium intake for longer duration is responsible for osteop...

Thickening of pulmonary interlobar fissures: exposure-response relationship in crocidolite and amosite miners.

Dust exposure and mortality in an American factory using chrysotile, amosite, and crocidolite in mainly textile manufacture.

This report describes the second in a series of three parallel cohort studies of asbestos factories in South Carolina, Pennsylvania, and Connecticut to assess the effects of mineral fibre type and industrial process on mortality from malignant mesothelioma, respiratory cancer, and asbestosis. In the present plant (in Pennsylvania) mainly chrysotile, with some amosite and a small amount of croci...
