Iron(III) complexes of alginate and pectate gels are photoreactive. Their Mossbauer spectra display features indicative of superparamagnetic relaxation of magnetically ordered iron oxyhydroxy nanoparticles. Analysis indicates that pectate and alginate gels differ both in the size distribution of the nanoparticles and in their coordination to carboxylate groups and suggests that smaller nanoparticles are generally more reactive.
