Abstract:
A method of preparing a gel from carboxymethyl cellulose alkali metal salt, which is an anionic cellulose derivative, by using acid or acid solution. To increase the strength and the elasticity of a gel, a water-insoluble metal compound or organic reinforcement is added when mixing. The obtained gel is one of environmentally friendly type gels because the raw material is derived from plant.
