Resumen:
Water is of fundamental importance for the life of all species and given the
problem of lack of water in the northeastern semi-arid one of the alternatives is to resort to
other sources such as underground wells and cisterns. With the increasing contamination of water
by various pollutants, which makes this resource increasingly scarce and unsuitable for the
use, there is a need to develop new treatment methods that are
accessible, efficient, renewable and that do not produce polluting waste that degrades the
environment. Due to this, the use of natural adsorbents has become one of the
most investigated alternatives for water treatment are to remove pollutants
organic or inorganic. The present study aims to develop methodologies
analytical methods using column chromatography, and as adsorbent the husk and seed of the
passion fruit (Passiflora edulis) and the performance of physical-chemical tests in aqueous samples.
Measurements of pH, turbidity, electrical conductivity, hardness, solids
total dissolved and chloride levels. After analyzing the samples, it was observed that the
values obtained are in accordance with the standards established by ordinance 2914/11 of the
Ministry of Health, with the exception of the pH index, turbidity and total dissolved solids, the
which in some samples were outside the indicated standards. About
methodology used, it was possible to observe an improvement in the turbidity and
electrical conductivity of the water collected to values within the predicted by the Ordinance
2914/11 of the Ministry of Health for water for human consumption, therefore, this
methodology can be used for the reuse of industrial effluents that need to go through
a slowing down process.
