Saponification of Adsorbent BLPAMA

Abstract:

Article Preview

The saponification conditions for bentonite/sodium lignosulfonate graft acrylamide and maleic anhydride adsorbent composites (BLPAMA) prepared by solution polymerization were studied in detail. The results had shown that the optimum conditions of saponification were that the concentration of NaOH (CNaOH) = 1.0mol/L, the temperature (T) = 90°C and the saponification time (t) = 1.5h. And the maximum adsorption quantity of saponified BLPAMA to Pb2+ was 1.304mmol/g in the Pb2+/Cu2+ binary metal solution.
