Polyvinyl Alcohol / Fulvic Acid Composite Adsorbent Gel Prepared by Microreactor
Abstract
Polyvinyl alcohol/fulvic acid (PVA/FA) composite hydrogel was synthesized in a microreactor using fulvic acid and polyvinyl alcohol as raw materials. The adsorption properties of the composite hydrogels for Pb2+ in water were investigated. The results show that the PVA/FA composite hydrogel is a three-dimensional porous network structure with uniform pore distribution and long-time water stability. When the mass fraction of fulvic acid was 1.5% and the freeze-thaw times were 3 times, the rate of saturated adsorption of PVA/FA composite hydrogels could be reaching to 72.3%.
