Carbamazepine and Diclofenac Removal Double Treatment: Oxidation and Adsorption.

In the present research, the effect of two hybrid treatments, ozone followed by powdered activated carbon (PAC) or PAC followed by ozone (O), was studied for the removal of two drugs present in water: diclofenac and carbamazepine. In the study, two initial concentrations of each of the contaminants, 0.7 mg L and 1.

[Mortality among workers in metallurgical industry: literature review.].

Background: The analysis of mortality offers an important indicator for assessing the state of workers' occupational health. Workers involved in the extraction, refining, alloying and manufacturing of metals are frequently exposed to occupational risks that can lead to their death. The objective of this work was to synthesize the scientific evidence about factors associated with mortality among workers in the metallurgical industry.

Efficacy of atrazine pesticide reduction in aqueous solution using activated carbon, ozone and a combination of both.

In this study, the reduction of the emerging organic contaminant atrazine in water, was investigated by adsorption, oxidation and a combination of both technologies. Adsorption tests were performed using method ASTM D3860-98 with two types of activated carbon: powdered activated carbon and granular activated carbon. For the oxidation tests, advanced ozone oxidation technology was used.

The use of combined treatments for reducing parabens in surface waters: Ion-exchange resin and nanofiltration.

In this study, the removal of parabens from waters, using a combined treatment of magnetic ion exchange resins and subsequent filtration through nanofiltration membranes, was investigated. The selected parabens were methylparaben, ethylparaben, propylparaben and butylparaben. Two different magnetic anionic exchanger resins, MIEX® DOC and MIEX® GOLD, and two nanofiltration membranes (NF), NF-90 and DESAL-HL, were tested.
