Avaliação de um meio adsorvente a partir da Moringa oleifera Lam para uso no tratamento de água produzida

Abstract

The produced water, originated from the extraction and production of petrolium, has a high content of oil and grease, so, due to this factor the necessity of treatment. The study is to develop a treatment of water produced using two byproducts of crushed Moringa oleifera Lam, acting as a means adsorbent for removal of TOG: the full crushed pod (with seed) and the crushed pods without seed and without the spongy part of moringa. To analyze the design efficiency a chemical study was done on laboratory scale with the aid of the BET Analysis and it was concluded that Sample B obtained a better choice because it showed a high surface area, how bigger is the surface area of the adsorbent, higher is their interaction with the adsorbate. To the total pore volume, the Sample B showed better results, how greater is the volume, better is the adsorbent function. With the provided data was possible to construct the adsorption and desorption isotherms for each sample, the samples A and B are classified in mesopores (2-50 nm), according to IUPAC. From the results, and comparisons with products used, was observed the efficiency of the byproducts of Moringa oleifera Lam as adsorbent means that can replace them in the industry as an alternative means.
