Kinetic study of Hubnerite (MnWO4) chlorination
(Elsevier Science, 2012-05-23)
The kinetics of Argentinean Hubnerite (MnWO 4) chlorination using gaseous chlorine as chlorination agent was studied between 750 and 950 °C. The relative mass change during the chlorination reaction was continuously monitored ...
Extraction of lithium from beta-spodumene using chlorination roasting with calcium chloride
(Elsevier, 2015-02)
Chlorination roasting was used to extract lithium as lithium chloride from β-spodumene. The roasting was carried out in a fixed bed reactor using calcium chloride as chlorinating agent. The mineral was mixed with CaCl2 on ...
Kinetic study on the chlorination of β-spodumene for lithium extraction with Cl2 gas
(Elsevier, 2013-04-10)
In this paper, the kinetics chlorination of -spodumene for the extraction of lithium has been studied using gaseous chlorine as chlorinating agent. The effect of chlorine flow rate, temperature, mass of the sample, and ...
A Panoramic Overview of Chlorination and Carbochlorination of Light Rare Earth Oxides, Including Thermodynamic, Reaction Mechanism, and Kinetic Aspects
(Springer, 2021-12)
Chlorination and carbochlorination processes have industrial applications in metallurgical activity for extraction and purification of uncommon metals such as rare earth elements (REE). This study reviews the chlorination ...
Chlorine disinfection of dye wastewater: Implications for a commercial azo dye mixture
(2013-01-01)
Azo dyes, the most widely used family of synthetic dyes, are often employed as colorants in areas such as textiles, plastics, foods/drugs/cosmetics, and electronics. Following their use in industrial applications, azo dyes ...
Chlorin, phthalocyanine, and porphyrin types derivatives in phototreatment of cutaneous manifestations: A review
(2019-08-02)
Recent scientific research has shown the use of chlorin, phthalocyanines, and porphyrins derivatives as photosensitizers in photodynamic therapy in the treatment of various pathologies, including some of the major skin ...
Thermogravimetric analysis of polycarbonates and polythiocarbonates with chlorinated aromatic side-rings
(1990)
The thermal stability and kinetics parameters of polycarbonates and polythiocarbonates derived from diphenols with chlorinated aromatic side-rings were studied. The polycarbonates exhibited a higher thermal stability than ...
