K-Carrageenan-Nickel adsorbant bead have been synthesized with different concentrations of Ni. New image processing software was developed to investigate the appearance of synthesized adsorbent and study of Ni concentration effect on the shape of adsorbent beads. The shape of adsorbents was observed by mean of optical microscope and the results were analyzed by image processing. The size distribution of polymer beads was 128-168 μm and the eccentricity of the adsorbent particles was decreased up to 18g addition of Ni in the slurry.
