Estudo da capacidade de adsorção de carvão de palete

Abstract

Pallets are widely used for moving cargo, however, they are often disposed of inappropriately, due to the cost associated with their correct disposal. This study focused on transforming expired pallets into pallet charcoal (PC) and investigating its properties, determining the Langmuir and Freundlich isotherms, using primary standard oxalic acid solutions. The gravimetric yield achieved was 66.05%, which indicates excellent cost/benefit. The isotherms characterized that adsorption was favorable with CP, with saturation of the sites occurring at around 0.014 g.L-1, with a layer close to a concentration of 3.3 mol.L-1. The active area of the CP was estimated at 715.94m2.g-1. This study was dedicated to evaluating the adsorption capabilities of discarded material, aiming for its reuse in a more sustainable way, thus contributing to the preservation of the environment. Transforming discarded material into an adsorbent not only adds value to the product, but also significantly reduces industry costs associated with conventional disposal.
