Acid dyes adsorption onto activated carbon from waste tyres
Activated carbon has been produced from waste tyres using chemical treatment. The effects of activation chemical used, chemical ratio, soaking time in the impregnation step, activation temperature and time duration of the activation step were investigated. Surface area, pore size distribution, total pore volume, adsorption capacities of acid dyes (AY117 & AB25) were determined. The carbon product ...

Cd(II) removal on surface-modified activated carbon: equilibrium, kinetics and mechanism
Commercial pulverous activated carbon (AC-0) was modified through two steps: oxidize AC-0 acid firstly, impregnate it with iron using ferric chloride secondly. Orthogonal experiment was conducted then to prepare modified activated carbon with high Cd(II) adsorption capacity (ACNF). Batch adsorption experiments were undertaken to determine the adsorption characteristics of Cd(II) from aqueous ...

Corrosion protection in a pulp and paper industry - UPM Fray Bentos, Uruguay - Case Study
It is widely accepted that corrosion has an important economic impact at an industrial scale. As an example, results of a study carried out in the US showed that the total annual estimated direct cost of corrosion in the country was $276 billion, which was approximately 3.1% of the nation’s Gross Domestic Product (GDP). Thus, within the last few decades, an important effort has been made ...
