SUMMARY:

Polyurethanes (PU's) are a varied class of polymers whose applications can occurin several industrial segments (LIMA, 2007). Pu's can be obtained by reusing diisocyanato with a polyol, usually of petrochemical origin (COSTA, 2007). In literature studies are presented related to the production of polymers from renewable sources, in substitution of petroleum-based raw materials and which generate environmental impacts (FERRARO, 2017).

The use of vegetable oils for polyol synthesis is a strong attraction in the chemical products because they represent abundant raw materials, mostly nontoxic, lower production waste during the processing phase, low production and processing cost and be biodegradable (COSTA, 2007).

Polyurethanes can be used in the form of flexible foams, which commonly open cells, being air-permeable, reversible to deformation, and can be produced in a wide range of properties including softness, firmness and resilience (ACCIOLY, 2008).

 

Flexible foams are common materials and have adsorbent characteristics, and can be be used in different applications such as the adsorption of herbicides and dyes in water (VINHAL, 2017; KAMPRAD; GOSS, 2007).
Adsorption is a physical-chemical phenomenon of adhering, essentially surface, being observed when a liquid or gaseous phase component is transferred to the surface of a (NUNES, 2014). 

This phenomenon is a potentially versatile and for the removal of toxic substances from aqueous sources and for the treatment of various types of effluents, such as effluents rich in pharmaceutical compounds (MARSALEK, 2020). Drugs of various classes have been found in hospital effluents and ETEs, in groundwater and potable water at varying concentrations (HARO, 2017).

The removal of these pharmaceutical substances from the environment is necessary because the high consumption of associated with incorrect disposal, has irreversible impacts such as, in the face of for example, bacterial resistance. (HARO, 2017). The adsorption process stands out in this context for being is a widely studied and promising possibility for the removal of these substances from aquatic sources (MARSALEK, 2020).

This project aims to study the adsorptive capacity of paracetamol in solution polyurethane foams produced from three distinct vegetable oils. The foams will be produced by the in shot mechanism structurally characterized and submitted to experiments of adsorption assisted by statistical techniques of design of experiments (DOE).
