Study on the Desorption Performance of Feather as a New Adsorption Material on Pb2+

Qi Ren, Hong Wang

Abstract

In this paper, feather was used to adsorb lead ions as a new type of adsorbent materials. For recycling feather, NaOH solutions as the desorption solutions were adopted to desorb feather after adsorption of lead ions, and then the factors which affect the desorption effect, such as desorption time, concentration of desorption solutions, temperature and so on were studied. It was found that the optimum desorption conditions are: the desorption time of 60min, the concentration of NaOH solutions of 30mmol/L, the temperature of 40°C.
