Abordagem experimental da força de atrito em aulas de Física do Ensino Médio

In this paper we propose and describe the performance of an experimental activity to address the concept of friction in High School Physics practical classes. We use a low-cost and simple construction device that enables the determination of the coefficient of static friction between two materials through three different procedures. The results were coherent, with small percentage deviation, which gives reliability to the activity and can stimulate discussions in class. The activity also allows greater contextualization of concepts that are usually discussed only theoretically, requiring a higher abstraction level of the students. This can stimulate discussions and greater interaction between teacher and students.

Estudo da utilização de serragem de madeira como adsorvente para o tratamento de efluentes têxteis

The Brazilian textile industry has been a highlight in the global economy. Connected with this high economic performance there is the water consumption and the generation of great volumes of wastewater which present high concentrations of dyes and chemical substances. One of the main techniques used in the treatment of textile effluents is adsorption, which has the activated carbon as the main adsorbent. Recently, studies have been developed to find alternative materials to activated carbon and exhibiting good adsorption capacity of dyes. The aim of this work is to study the potential of sawdust as adsorbent of low cost to remove the dye Direct Green 26. The results of this type of dye removal were obtained through the study of adsorption isotherms obtained by spectrophotometry in the UV-visible region analyzed by the Langmuir model. Finally, a comparison was made of these results with those of other adsorbents. Results showed that the average removal of dye, using sawdust, was 78.8% for an initial concentration of 500mg / L and the maximum adsorption capacity of 119mg / g. These results demonstrate the great potential of sawdust as an adsorbent for the dye Direct Green 26.
