Abstract:
The method of preparing stable cellulosic fiber material for use in forming zeolite/cellulose composites comprising the steps of:(a) suspending loose cellulose fibers in an aqueous solution of a compound selected from the group consisting of alkali metal and alkaline earth metal hydroxides and silicates; (b) stirring the resulting suspension until it reaches a macroscopically homogeneous appearance; (c) heating the resulting mixture at a temperature of approximately 323-423 K until only dry solids remain; (d) contacting the resulting mixture with excess distilled water to remove physically adsorbed or trapped compound of step (a) from said fibers; and (e) heating the resulting fiber material at a temperature of approximately 323-423 K to dry said fiber material.
