In order to improve the utilization of industrial alkaline lignin and expand its application scope,with alkaline lignin and polyvinyl alcohol( PVA) as primary materials, formaldehyde as crosslinker,potassium sulfate and magnesium sulfate added,alkaline lignin / PVA cross-linked slow-release film was prepared by casting. The reaction film was characterized by FTIR-ATR. Release performance for K and Mg from alkaline lignin / PVA cross-linked film was measured by leaching experiment. The results showed that:( ...
