ABSTRACT:
The present invention features methods of making absorbent material which exhibit excellent absorption for saline and other liquids as well as being biodegradable. The methods of the invention form a particulate which can be stored in dry form and rehydrated at any time. The particulate can be used to replace the presently utilized polyacrylate superabsorbers. The base material used in the methods of the invention is a carboxylated cellulosic material such as carboxymethylcellulose, preferably, a carboxymethylcellulose having a DS, or Degree of Substitution, of 0.5 or greater. The carboxylated cellulose material is reacted with two distinct agents; a cross-linking agent and a hydrophobicity agent to make the final absorbent.
