Abstract
The invention discloses a method for preparing manioc waste super absorbent resin. According to the method, manioc waste and acrylic acid are used as raw materials, a cross-linking agent of N,N-methylene-bis-acrylamide and an initiating agent of potassium peroxydisulfate are added, and the mixture is reacted for a certain time under protection of nitrogen by controlling proper temperature, dried and smashed to obtain a manioc waste super absorbent resin finished product. The method for preparing the manioc waste super absorbent resin is simple in preparation process, low in cost, green and environmentally friendly. By utilizing the method, additional value of the manioc waste is effectively improved, manioc planting and processing and development of related industries of China are helped to be promoted, environmental pollution is reduced, and obtained products meet national standards.
