1. INIBIÇÃO À CORROSÃO DE AÇO-CARBONO EM MEIO SALINO PELO HETEROCICLO ISATINA VEICULADO EM MICROEMULSÕES
Polar microemulsion systems (SME) based on saponified coconut oil (OCS) as surfactant were prepared in order to increase the solubility of the heterocycle isatin (IST) aiming at its application as corrosion inhibitor against AISI 1020 mild steel, in saline medium. The adsorptions phenomena of the tested SME systems (SME-OCS1-IST and SME-OCS2-IST) in the liqu

2. Reciclagem de material asfáltico fresado utilizando solventes e microemulsões
With the increase of asphalt milling services was also a significant increase in recycling services pavements. The techniques used today are basically physical processes in which the milled material is incorporated into new asphalt mixtures or executed on site, with the addition of virgin asphalt and rejuvenating agent. In this paper seeks to analyze the eff

3. Reavaliação da eficiência de óleo de coco saponificado e de sua microemulsão como inibidores de corrosão em uma célula eletroquímica
An interesting development in surfactants science and technology is their application as corrosion inhibitors, since they act as protective films over anodic and cathodic surfaces. This work aims to investigate the efficiency of saponified coconut oil (SCO) as corrosion inhibitor and of microemulsified system (SCO + butanol + kerosene oil + distilled water),

4. Estudo comparativo da eficiência da difenilcarbazida e do óleo de coco saponificado microemulsionados na inibição da corrosão de aço carbono
The effectiveness of microemulsions (ME) of saponified coconut oil (OCS-ME) and diphenylcarbazide (DC-ME) on a carbon steel corrosion inhibition process was evaluated using an electrochemical method of polarization resistance. The ME was prepared with OCS, butanol, kerosene and saline solutions. OCS-ME and DC-ME showed highest inhibitions effects (77% and 92

5. Estudo da influência de tensoativos em sistemas microemulsionados na extração de gálio e alumínio
Gallium is an important material used in the electronic industry whose demand in the world market is increasing in view of its potential applications. A selective technique is required to allow for the production of the metal, separated from aluminium. Due to the fact that microemulsions constitute an attractive alternative to metal extraction procedures, mi

6. Utilização de microemulsões como agentes modificadores de superfícies para remoção de íons metálicos
The heavy metals are used in many industrial processes and when discharged to the environment can cause harmful effects to human, plants and animals. The adsorption technology has been used as an effective methodology to remove metallic ions. The search for new adsorbents motivated the development of this research, accomplished with the purpose of removing C
