Determinação de propriedades físico-químicas da água do rio Piranhas-Açu com “clean-up” por cromatografia em coluna.

Abstract

Water is fundamental for humans and other living things. Their existence is of utmost importance for the preservation of life. It is used for human consumption, social and economic activities. The Piranhas-Açu River is important for the development of the states of Paraíba and Rio Grande do Norte. The river, after crossing part of Paraíba, arrives at Jardim de Piranhas - RN bringing in its aquatic beds an amount of pollutants that can be harmful to the environment and to the residents who depend on this water for survival. Some industries in the textile sector and sanitary sewers discharge their industrial effluents into the river without any treatment. For the improvement of this water, methods of water treatment and removal of these pollutants are necessary. The present study had the objective of evaluating the physicochemical patterns of water quality of the Piranhas-Açu river before and after the use of column chromatography using a natural adsorbent (passion fruit peel) to treat water. And check the quality of the matrix and compare the potability values established by Ministry of Health Order No. 5/2017. Physico-chemical analyzes of the water will be carried out with pH, electrical conductivity and turbidity measurements, as well as chloride, total hardness and sodium and potassium concentrations in the Flame Photometer and to evaluate the efficiency of the natural adsorbent in the purification of water quality.
