1. CHARACTERIZATION-PERFORMANCE OF ZnO AND ZnO/ZnFe2O4 CATALYST USING ARTIFICIAL AND SOLAR LIGHT FOR MERCURY (II) REDUCTION
Abstract This study describes the application of ZnO commercial oxide and ZnO/ZnFe2O4 mixed oxides to reduce the mercury ion (Hg2+) in the aqueous phase. The catalysts synthesized were characterized by thermogravimetric analysis, adsorption and desorption of N2, scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, photoac

2. ESTUDO DE UM REATOR SOLAR HÍBRIDO PARA CURA ACELERADA DO CONCRETO EM ÁGUA MORNA. / STUDY OF A HYBRID SOLAR REACTOR FOR ACCELERATED CURING OF CONCRETE IN WARM WATER.
The Portland cement concrete material is the most consumed after the water worldwide due to their versatility molding, strength and durability as a structural material. The curing is the procedure that aims to keep the concrete saturated with water in their early ages and it is essential to ensure the reactions of cement hydration, promoting its consolidatio

4. Tratamento de efluente tÃxtil utilizando o processo foto-fenton / Treatment of textile effluent using photo-fenton process
The aim of this work was to study the performance of the photo-Fenton process using both the artificial UV and solar sources on the textile effluent treatments. Preliminary photo-Fenton experiments for mineralization and degradation of organic and inorganic pollutants as well as of synthetic dyes were carried out in order to assess the best experimental cond

5. Degradação de 2,4-diclorofenol em solução aquosa por meio de processo fotoquímico solar. / Degradation of 2,4-dichlorophenol in aqueous solution by means of solar photochemical process.
2,4-dichlorophenol (2,4-DCF), the model pollutant selected in this work, is a compound used in the production of pesticides, herbicides, antiseptics, and commonly found in industrial wastewaters. It is considered a priority pollutant due to its high toxicity and high persistence in the environment. This study investigated the degradation of 2,4-DCF in a tubu

6. Desenvolvimento de um sistema foto-oxidativo visando aplicação no tratamento de águas produzidas em campos de petróleo
A crescente preocupação com o meio ambiente, além de leis cada vez mais rígidas para quem polui, tem feito as indústrias buscarem alternativas para o tratamento de seus resíduos. Nos últimos anos, a indústria de petróleo, especificamente, tem procurado meios de remediar um de seus maiores problemas ambientais: o descarte abundante das águas produzi

8. Experimental study and mathematical modeling of hybrid solar reactor for phenol degradationby photo-Fenton process. / Estudo experimental e modelagem matemática de reator solar híbrido para degradação de fenol em solução aquosa pelo processo foto-Fenton.
Wastewaters containing hazardous, or recalcitrant organic substances are generated in a wide variety of industrial processes. The inadequate management of these effluents can cause contamination of underground and surface water. Their treatment by conventional processes may not be technically efficient, and usually prevents effluents from being discarded or

9. Pos-tratamento de esgoto por fotocatalise heterogenea solar antes e apos filtração lenta / Post-treatment of sewage by solar heterogeneous photocatalysis before and after slow filtration
Currently, techniques for reuse of water using renewable energy sources and building materials at low cost are used in small scale to serve needy populations in sanitation in order to minimize transmission of diseases and water contamination from chemical compounds harmful to human health. The advanced oxidative process (AOP) is a technology developed to min

10. Use of solar energy in the treatment of water contaminated with phenol by photochemical processes
The solar driven photo-Fenton process for treating water containing phenol as a contaminant has been evaluated by means of pilot-scale experiments with a parabolic trough solar reactor (PTR). The effects of Fe(II) (0.04-1.0 mmol L-1), H2O2 (7-270 mmol L-1), initial phenol concentration (100 and 500 mg C L-1), solar radiation, and operation mode (batch and fe

11. New limits for the violation of the equivalence prinriple on solar neutrinos / Novos limites para violação do principio da equivalencia em neutrinos solares
In this work, we studied the model for the violation of the equivalence principle (VEP) on solar and reactor neutrinos. This model was already considered as a promising solution to the solar neutrino problem (SNP), but was abandoned because it wasn?t able to explain all the data with a single set of physical parameters. The mass- avor mixing model, together

12. Degradação fotoquímica de efluentes industriais contendo polipropileno e isoniazida
One of the main impacts to the environment is the water pollution, where the industrial sector is one of the main sources of this problem. In order to search for a solution, the industrial sector is looking forward to new technologies to treat its wastewaters with the goal to reuse the water in the own process. In this mode, the treatment presents a reductio
