| abstract | A polyurethane production process employing biopoliol obtained by chemical modification of vegetable oil and adsorbent biomass obtained by it. The present application for provincial invention discloses the development of rigid polyurethane polymers obtained from polyols derived from mabea fistulifera mart oil. The chemical modification of the oil occurred through an in situ hydroxylation reaction using acetic acid, hydrogen peroxide and sulfuric acid. The synthesized pu-3 polymer was used in the adsorptive assays, as it presented potential for dye removal in aqueous solution. adsorption studies of direct red 80 (dr80) and reactive blue 21 (rb21) dyes by the pu-3 polymer included; equilibrium, kinetic and thermodynamic studies. Langmuir and Freundlich models were used to characterize the adsorbent / dyes system. the maximum capacity stipulated using langmuir is 10.37 mg.g ^ -1 ^ for dr80 and 13.54 mg.g ^ -1 ^ for rb21 under ph conditions adjusted to 2.0 and 25 <198> c . The adosrption process follows the pseudo-second order kinetics for both dyes. thermodynamic parameters showed that the adsorption process is spontaneous and endothermic (positive <30 h <198>) and favorable (negative <30> g <198>). The developed adsorption process was applied to a real industrial effluent sample containing rb21 and dr80 and a removal percentage of 94.5% for rb21 and 100% for dr80 were found after treatment. |
