A study on barium ferrite particles in carrageenan hydrogels showed a modulus decrease of about 75 % (from 20 MPa) on magnetization at 800 KA/m [151]. Strains of about 0.2 % could be produced in these gels. This effect is clearly not the same as that seen in the iron-filled elastomers since it is larger, in the opposite direction and irreversible.

We have been interested in immobilizing different adsorbents such as activated carbon powder and ion-exchange resins in hydrogels such as calcium alginate or potassium carrageenan. The... 

The use of small affinity adsorbent particles immobilized in hydrogel beads has been proposed to circumvent some of these problems (1). The hydrogel matrix can be provided by Ca-Alginate, K-Carrageenan or any other reversible gel. Previous research in our laboratory has indicated that significantly higher adsorption rates and overall adsorption capacities can be achieved by using immobilized affinity adsorbent beads in the whole broth. These beads provide low overall internal mass transfer resistance due to the...
