Optimization of the Lead Adsorption Process with Modified Chitosan for being used in the Treatment of Water

In this study, chitosan extracted from Penaeus Vannamei shrimp was modified to prepare two adsorbent materials: chitosan-glutaralaldehyde (QGD) and chitosan-ferric nitrate (QFe). Effects of the pH, dosage of adsorbent, stirring speed, temperature and contact time were evaluated. The best lead adsorp...

Effects of the pH, dosage of adsorbent, stirring speed, temperature and contact time were evaluated. The best lead adsorption was found to occur onto QGD at pH 6,75-7,00; dosage of adsorbent 0,35-0,50g and time of contact 151-175min. The efficiency of lead remotion with QGD was 98,40% and the isothermal study of adsorptive capacity showed an absorption of 282,61mg of Pb2+ per g of QGD.En este estudio, el quitosano fue extraído y modificado a partir de caparazones de camarón Penaeus Vannamei con el cual se prepararon dos materiales adsorbentes: quitosano-glutaraldehído (QGD) y quitosano-nitrato férrico (QFe). En la primera etapa experimental fue seleccionado el material adsorbente (QGD) que presenta un mayor porcentaje de adsorción. En las etapas experimentales posteriores son analizadas las influencias de factores como el pH, la dosificación del adsorbente, velocidad de agitación, temperatura y tiempo de contacto en la adsorción de plomo en QGD; estableciéndose en la optimización que son determinantes: el pH, la dosificación del adsorbente y el tiempo de contacto en un rango de 6,75-7,00; 0,35-0,50 g y 151-175 min respectivamente.
